catena-Poly[zinc(II)-μ-aqua-κ2O:O-bis(μ-quinoline-4-carboxylato-κ2O:O′)]

The asymmetric unit of the title complex, [Zn(C10H6NO2)2(H2O)]n, consists of one quinoline-4-carboxylate anion, half of a Zn2+ cation and half of a coordinated water molecule. The cation and the water O atom have crystallographically imposed inversion and twofold rotation symmetry, respectively. The metal centre displays an elongated ZnO6 octahedral coordination geometry provided by the O atoms of four anions at the equatorial plane and two axial water molecules. Each anion and water molecule act as bridges between ZnII cations, forming a polymeric chain parallel to [001]. The chains are further linked into a three-dimensional framework through O—H...N hydrogen bonds
