Abstract
In this work, benzimidazole (Hbim) and Cu(II) ions ligands were chosen as building blocks to produce a novel Cu(II) compound (CP) based on {Cu4O}cluster, namely, [Cu4OCl6(Hbim)4]n·n(H2O)·2n(EtOH) (1). The investigation of SCXRD reveals that the CP 1 is a separated 0D structure based on tetrahedral {Cu4O} clusters. Furthermore, this supramolecular frame displayed superior photocatalytic effect on the photodegradation of MB under UV light irradiation.

Abstract
Water plays a vital role in all aspects of life. Recently, water pollution has increased exponentially due to various organic and inorganic pollutants. Organic pollutants are hard to degrade; therefore, cost-effective and sustainable approaches are needed to degrade these pollutants. Organic dyes are the major source of organic pollutants from coloring industries. The photoactive metal-organic frameworks (MOFs) offer an ultimate strategy for constructing photocatalysts to degrade pollutants present in wastewater. Therefore, tuning the metal ions/clusters and organic ligands for the better photocatalytic activity of MOFs is a tremendous approach for wastewater treatment. This review comprehensively reports various MOFs and their composites, especially POM-based MOF composites, for the enhanced photocatalytic degradation of organic pollutants in the aqueous phase. A brief discussion on various theoretical aspects such as density functional theory (DFT) and machine learning (ML) related to MOF and MOF composite-based photocatalysts has been presented. Thus, this article may eventually pave the way for applying different structural features to modulate novel porous materials for enhanced photodegradation properties toward organic pollutants.

Abstract
A 2-dimensional Pb(II) metal-organic framework, [Pb(bdc)0.5(py-Phen)NO3]n (SM-3), was synthesized under solvothermal conditions using a mixed ligand approach. SM-3 was assembled using dinuclear SBUs [Pb2(COO)2]2-, an oxygen donor H2bdc = 1,4-benzene dicarboxylic acid, and nitrogen donor py-Phen = pyrazino[2,3-f][1,10]-phenanthroline linkers. SM-3 was characterized by elemental analysis, FT-IR, powder-X-ray diffraction, thermal gravimetric analysis, SEM, EDS, TEM, and single-crystal X-ray diffraction techniques. Crystallographic studies confirmed that SM-3 displays a 2D layered structure with unique anagostic (Pb⋯H) interactions. Interestingly, the presence of abundant π-electron-rich rings embellished with free -N donor sites in the framework makes SM-3 an excellent adsorbent that exhibits adsorption performance for iodine and dyes. The experimental results show that SM-3 reversibly adsorbs radioactive iodine in the solution and vapor phases and exhibits selective adsorption performance for hazardous cationic dyes, namely, methylene blue (MB) and rhodamine-B (Rh-B), from aqueous solution. Moreover, the possible mechanism of iodine and dye adsorption was also discussed in detail. Thus, this work is remarkable for coordination chemists to engineer layered MOFs for adsorption purposes and expands their potential characteristics by converting them into 2D MOF nanosheets to further enhance the adsorption of hazardous pollutants for environment protection.

Abstract
Coordination compounds have undergone booming development in the past 20 years for their applications as multifunctional materials in the field of catalysis and biomedicine. To create compounds with both catalytic and bioactive properties, we selected Cu(II) ion and benzimidazole (Hbim) ligand as the building blocks to fabricate a new cluster-based Cu(II) compound [Cu4OCl6(Hbim)4]n·n(H2O)·2n(EtOH) (1). The exploration of single crystal X-ray diffraction exhibits that complex 1 is a 0D isolated structure on the basis of tetrahedral {Cu4O} clusters. Moreover, such supramolecular framework not only shows excellent photocatalytic effect for the MB photodegradation under the irradiation of ultraviolet light but also has the application values against orbital wall fracture. This work gives new insights on the creation of coordination polymers which might be potentially used as photocatalytic and bioactive reagents.

Abstract
Two new metal-organic compounds, namely [Cu(CrO4)(4,4'-bipy)(H2O)]·n(H2O) (1) together with [Mn(Cr2O7)(bpp)2]n (2) (4,4'-bipy is 4,4'-bipyridine and bpp is 1,3-bis(4-pyridyl)propane), were hydrothermally generated, which were characterized structurally through a series of characterization techniques. Moreover, compounds 1 and 2 have 2.95 eV and 3.02 eV of narrow optical band gap values, and possess outstanding photocatalytic effects for the methylene blue degradation under irradiation of visible light. The application of above compounds in the ophthalmic local anesthesia was examined and the specific mechanism was tested. First of all, the acetylcholine content in the synaptic cleft was measured with enzyme linked immunosorbent assay (ELISA) assay after treated with the CPs. The acetylcholine receptor relative expression on nerve cells was subsequently measured via real time reverse transcription-polymerase chain reaction (RT-PCR) under the treatment of compounds. In the end, the complexes' toxicity was evaluated by Cell Counting Kit-8 (CCK-8) detection.

Abstract
The stimulus to the modeling of enzyme functioning sites comes from their potential to give insight into the natural enzyme's mechanistic pathways, ascertain the role of that different metal ion in the active site and construct better catalysts motivated by nature. The presence of metal ion leads to the activation of molecular oxygen in the metalloenzymes. The metalloenzymes such as the catechol oxidase (CO) enzyme that oxidizes the catechol to corresponding quinones which eventually protect damage tissues from plant and pathogen. Thus, the design and characterization of catalysts used as selectively and efficiently oxidation reactions have grown to be unique challenges for modern inorganic chemists. In this work, two novel tetranuclear complexes (1 and 2) have been synthesized in excellent yield. The complexes were characterized using various spectroscopic techniques such as FTIR, UV-Visible and PXRD pattern. The structure of 1 and 2 was elucidated by SC-XRD (single crystal X-ray diffraction) analysis. The magnetic study reveals the presence of the antiferromagnetic nature of 1 and 2. Both 1 and 2 shows a very good catecholase-like activity by oxidizing the catechol to analogous quinone in methanolic solution. Thus, a structure-activity relationship can further help us design other substituted tetranuclear complexes with enhanced catecholase like activity.Communicated by Ramaswamy H. Sarma.

Abstract
There is an increasing demand for monitoring environmental pollutants and the control requires new sensing materials with better sensitivity, selectivity and reliability. In this study, a series of Co7 clusters incorporating various flexible polyhydroxyamine ligands are explored, with the first report of thiocyanate recognition triggered by crystal formation using a Co7 crystal (1). For this, we have fortunately synthesized three new mixed metal Co7 clusters with fascinating structural features. The clusters were characterized by spectroscopic and single crystal X-ray diffraction methods and later by DFT calculations. Due to its better emission spectrum, 1 was further utilized for evaluating its sensing ability towards various anions in water. Surprisingly, 1 shows better quenching ability towards the recognition of SCN− with a better binding constant. The luminescence quenching towards SCN− detection was further verified by the single crystal method, HSAB principle (symbiosis) and theoretical calculations such as DFT studies. The SCXRD data clearly suggest that the Co7 (1) can be converted into Co14 (1a) by direct reaction with NaSCN under ambient conditions. Besides the soft/hard acid–base concept (symbiosis), the energies of formation, and Co–NCS and Co–OH2 bond energies (as unravelled by DFT) are responsible for this transformation. Therefore, 1 can be used as a selective and sensitive sensor for the detection of thiocyanate anions based on the fluorescence amplification and quenching method. Further, the designed cluster has also been utilized to detect anions in human blood samples to differentiate a smoker and a non-smoker. It has been concluded that the samples of smokers have a high degree of thiocyanate (∼12 or 9.5 mg L−1) in comparison to those of non-smokers (2–3 mg L−1). Thus, this kind of cluster material has high potentiality in the field of bio-medical science in future endeavours for identification of the extent of thiocyanate content in smokers. A new Co based sensor for thiocyanate recognition by formation of the dimeric crystals is designed to distinguish a smoker from a non-smoker.![]()
