title: catena-Poly[[(dichloridozinc)-μ-4,4'-bis-(1H-imidazol-1-yl)biphenyl-κ(2)N(3):N(3')] 0.25-hydrate].
abstract: In the title one-dimensional coordination polymer, {[ZnCl(2)(C(18)H(14)N(4))]·0.25H(2)O}(n), the Zn(II) atom is coordinated by two chloride ions and two 4,4'-bis-(1H-imidazol-1-yl)biphenyl ligands, generating a distorted tetra-hedral ZnCl(2)N(2) geometry. The dihedral angle between the benzene rings of the ligand is 51.0 (1)° and the dihedral angles between the benzene rings and their attached imidazole rings are 18.7 (2) and 45.9 (1)°. The bridging ligand leads to [10-1] polymeric chains in the crystal and the disordered water mol-ecule (occupancy 0.25) forms O-H⋯Cl hydrogen bonds.
