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

ABSTRACT: The title coordination polymer, [CuCl(2)(C(8)H(8)N(4))(2)](n), arose from a layer-separated diffusion synthesis at room temperature. The Cu atom (site symmetry ) is coordinated by two chloride ions and four N atoms (two from triazole rings and two from pyridyl rings) in a distorted trans-CuCl(2)N(4) octa-hedral arrangement. The bridging 1-(4-pyridylmeth-yl)-1H-1,2,4-triazole ligands [dihedral angle between the triazole and pyridine rings = 68.08?(8)°] result in a two-dimensional 4(4) sheet structure in the crystal.
