Abstract
A new triazine ligand salt, 2,2′,2″-(1,3,5-triazine-2,4,6-triyl)tris(hydrazin-1-ium) chloride [THT·(HCl)3], and the one-dimensional coordination polymer of cadmium, [Cd2( µ-THT)( µ-Cl)( µ-I)I2]·2(H2O), are prepared and characterized by elemental analysis, Fourier-transform infrared spectroscopy, 1H NMR spectroscopy, and single-crystal X-ray diffraction (for the cadmium polymer). X-ray analysis revealed that the polymeric backbone is extended alternatively by di-iodo and di-chloro bridges; this type of bridge is not observed previously between any metal atoms. There are two types of cadmium atoms in the polymer: cadmium of the polymeric chain and terminal cadmiums. The geometry around the first (CdN2Cl2I2) is octahedral, while the latter (CdN3I2) has an incline to square-pyramidal geometry. The triazine ligand of this structure also bridges two cadmium atoms and acts as an N3 donor toward the terminal cadmium atoms and as an N2 donor toward the cadmium atoms of the chain. In the crystal network of the cadmium polymer, the hydrogen bonds of N–H···X (X: O, N, I) form different hydrogen bond motifs, including [Formula: see text](8), [Formula: see text](10), [Formula: see text](14), [Formula: see text](18), [Formula: see text](20), [Formula: see text](24), [Formula: see text](28), and [Formula: see text](32).

Abstract
Two complexes of N1-(2-aminoethyl)propane-1,3-diamine (AEPD), [Ni(AEPD)2](NO3)2 (1) and [Cu2( μ-Cl)2(AEPD)2](NO3)2·2H2O (2), are prepared and identified by elemental analysis, Fourier transform infrared spectroscopy and UV–Vis spectroscopy, and single-crystal X-ray diffraction (for 2). Spectral and structural data reveal that the AEPD ligand transfers from nickel to copper in the reaction between 1 and copper chloride. All coordination modes of the AEPD-based ligands are studied by analysis of the Cambridge Structural Database. The nickel atom in 1 has octahedral geometry (NiN6) while X-ray structure analysis revealed that the copper atom in the binuclear structure of 2 has an elongated square-pyramidal geometry with a CuN3OCl2 environment. In the crystal network of 2, water molecules and cationic complex units along with the nitrate ions form different hydrogen bond motifs. The thermodynamic stability of the compounds and their charge distribution patterns is studied by density functional theory and natural bond orbital analysis. The ability of AEPD and its complexes to interact with 10 selected biomacromolecules is investigated by docking calculations.

Abstract
A new asymmetrical Schiff base ligand, N1-(3-((pyridin-2-ylmethylene)amino)propyl)ethane-1,2-diamine, and its copper(II) complex, [Cu(PPEA)Br]Br·H2O (1), have been prepared. The copper complex has an elongated square pyramidal geometry with a CuN4Br environment. The thermodynamic stability of the compounds and their charge distribution patterns were studied by Density Functional Theory and natural bond orbital analysis. The ability of the ligand and its copper complex to interact with 10 selected biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS, Top II and B-DNA) was investigated by docking studies and compared with that of doxorubicin.
