catena-Poly[zinc(II)-μ-aqua-κO:O-bis-(μ-quinoline-4-carboxyl-ato-κO:O')].

The asymmetric unit of the title complex, Zn(C(10)H(6)NO(2))(2)(H(2)O), consists of one quinoline-4-carboxyl-ate anion, half of a Zn(2+) cation and half of a coordinated water mol-ecule. The cation and the water O atom have crystallographically imposed inversion and twofold rotation symmetry, respectively. The metal centre displays an elongated ZnO(6) octa-hedral coordination geometry provided by the O atoms of four anions at the equatorial plane and two axial water mol-ecules. Each anion and water mol-ecule act as bridges between Zn(II) cations, forming a polymeric chain parallel to [001]. The chains are further linked into a three-dimensional framework through O-H⋯N hydrogen bonds.
