In the title one-dimensional coordination polymer, {[ZnCl2(C18H14N4)]·0.25H2O}n, the ZnII atom is coordinated by two chloride ions and two 4,4′-bis­(1H-imidazol-1-yl)biphenyl ligands, generating a distorted tetra­hedral ZnCl2N2 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 mol­ecule (occupancy 0.25) forms O—H⋯Cl hydrogen bonds.
