Poly[dichloridobis[μ-1-(4-pyridylmeth-yl)-1H-1,2,4-triazole]copper(II)].

The title coordination polymer, [CuCl2(C8H8N4)2]n, arose from a layer-separated diffusion synthesis at room temperature. The Cu atom (site symmetry \overline{1}) is coordinated by two chloride ions and four N atoms (two from triazole rings and two from pyridyl rings) in a distorted trans-CuCl2N4 octa­hedral arrangement. The bridging 1-(4-pyridylmeth­yl)-1H-1,2,4-triazole ligands [dihedral angle between the triazole and pyridine rings = 68.08 (8)°] result in a two-dimensional 44 sheet structure in the crystal.
