Poly[dibromidobis[μ-1-(pyridin-4-ylmethyl)-1H-1,2,4-triazole-κ2N:N′]cadmium]

Abstract

The title coordination polymer, [CdBr2(C8H8N4)2]n, arose from a layer-separated diffusion synthesis at room temperature. The title compound is isotypic with the I and Cl analogues. The Cd atom, located on an inversion center, is coordinated by two bromide ions and four N atoms (two from triazole rings and two from pyridyl rings) in a distorted trans-CdBr2N4 octahedral arrangement. The bridging 1-(4-pyridylmethyl)-1H-1,2,4-triazole ligands are twisted [dihedral angle between the triazole and pyridine rings = 72.56 (13)°], affording a two-dimensional 44 sheet structure in the crystal.
