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 octa­hedral coordination geometry with four O atoms from two carboxyl­ate groups in bidentate chelating modes and two N atoms from a 1,10-phenanthroline ligand. The two terminal carboxyl­ate groups bind the Zn(II) ions, leading to a chain along the c axis. Adjacent chains are further linked by inter­molecular π–π inter­actions with a shortest centroid–centroid distance of 3.586 (3) Å, forming a two-dimensional supra­molecular architecture with (6,3)-network topology.
