Abstract:
The asymmetric unit of the title complex, [Zn(C(10)H(6)NO(2))(2)(H(2)O)](n), 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.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
