catena-Poly[(dichloridozinc)-μ-1-{4-[(1H-imidazol-1-yl)meth-yl]benz-yl}-1H-imidazole-κ(2)N(3):N(3')]

Abstract

The asymmetric unit of the title compound, [ZnCl(2)(C(14)H(14)N(4))](n), contains a Zn(II) ion situated on a twofold rotation axis and one-half of a 1-{4-[(1H-imidazol-1-yl)meth-yl]benz-yl}-1H-imidazole (L) ligand with the benzene ring situated on an inversion center. The Zn(II) ion is coordinated by two chloride anions and two N atoms from two L ligands in a distorted tetra-hedral geometry. The L ligands bridge ZnCl(2) fragments into polymeric chains parallel to [20-1].
