Abstract: 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.
