The construction, structures, and functions of pillared layer metal–organic frameworks

Pillared layer metal–organic frameworks (PL-MOFs), belonging to one representative of porous materials, have witnessed major advances in the past few years.

Syntheses, structures, and magnetic properties of three new cyano-bridged heterobimetallic chains based on [Fe(Tp*)(CN)3]−

Three, new, one-dimensional (1D) heterobimetallic cyano-bridged chain complexes of squares were prepared. The simultaneous presence of magnetic and porous properties have been found in compound 1–3.

Systematic design of secondary building units by an efficient cation-directing strategy under regular vibrations of ionic liquids

A cobalt-1,4-naphthalenedicarboxylic acid system in a systematic series of ionic liquids with different alkyl chain lengths of imidazolium cations governed the construction of four MOFs with regular changes of secondary building units (SBUs).

A series of multidimensional MOFs incorporating a new N-heterocyclic building block: 5,5′-di(pyridin-4-yl)-3,3′-bi(1,2,4-triazole)

By using a new N-heterocyclic building block: 4,4′-H₂dbpt, six novel coordination polymers with diversiform connectivity from one to three dimensional were constructed and characterized by X-ray crystallography successfully.

Coordination assemblies of the MII-tm/bpt (M = Zn/Cd/Co/Ni) mixed-ligand system: positional isomeric effect, structural diversification and properties

Six new coordination polymers with three positional isomeric bpt ligands and trimellitic acid (H₃tm), have been synthesized and characterized. They present diverse architectures. These results indicate that the versatile coordination modes of tm and the isomeric nature of bpt play crucial roles in modulating the structural topologies of these complexes.

Cu(II) Coordination Architectures with Two Positionally Isomeric Triazole–Bipyridine Ligands

The Cu(II) coordination polymer, {[Cu( p-bdc)(4,4′-bpt)]}n shows a 2D layer structure bridged by a p-bdc anion and the polymer {[Cu(H2btc)(3,3′-bpt)2(H2O)2]·2H2O}n, whose thermal stability has been briefly investigated, shows a 1D chain structure bridged by an H2btc anion. [ p-H2bdc = 1,4-benzenedicarboxylate acid, H4btc = 1,2,4,5-benzenetetracarboxylic acid, 4,4′-bpt = 1H-3,5-bis(4-pyridyl)-1,2,4-triazole, 3,3′-bpt = 1H-3,5-bis(3-pyridyl)-1,2,4-triazole] Both complexes have been prepared by the reaction of the relevant carboxylate acid and positional isomeric triazole–bipyridine ligand with Cu(II) salts under hydrothermal conditions. Both structures are further extended through intermolecular interaction to form 3D supramolecular frameworks.
