catena-Poly[[(1,10-phenanthroline)zinc]-μ-2,2'-oxydibenzoato]

In the title one-dimensional coordination polymer, [Zn(C(14)H(8)O(5))(C(12)H(8)N(2))](n), the Zn(II) ion is in a distorted octa-hedral coordination geometry with four O atoms from two carboxyl-ate groups in bidentate chelating modes and two N atoms from a 1,10-phenanthroline ligand. The two terminal carboxyl-ate groups bind the Zn(II) ions, leading to a chain along the c axis. Adjacent chains are further linked by inter-molecular π-π inter-actions with a shortest centroid-centroid distance of 3.586 (3) Å, forming a two-dimensional supra-molecular architecture with (6,3)-network topology.
