Supramolecular polymers of two novel 4-substituted-1,2,4-triazolate complexes: [Cd((P)Cltrz)(2)(NCS)(2)(H2O)(2)] and [Cu(4-atrz)(4)(Cl)(0.5)(H2O)(0.5)]center dot(ClO4)(1.5)((P)Cltrz : 4-(p-chlorophenyl)-1,2,4-triazole; 4-atrz : 4-amino-1,2,4-triazole

摘要

The synthesis and structural characterisation of two novel complexes of 4-substituted-1,2,4-triazoles, namely [Cd((p)Cltrz)(2)(NCS)(2)(H2O)(2)] (1) and [Cu(4-atrZ)(4)(Cl)(0.5)(H2O)(0.5)].(ClO4)(1.5) (2), are described. Elemental analysis, IR spectra and X-ray crystal structure analysis were carried out to determine the compositions and crystal structures of two compounds. The cadmium atom in 1 has a distorted octahedral coordination and forms one-dimensional chains via hydrogen bonding contacts. 2 has a distorted pyramid environment at the copper atom and a unique double-layer supramolecular structure connected via hydrogen bonds.
