catena-Poly[[(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)zinc(II)]-μ-2,2′-oxydibenzoato-κ2O:O′]

Abstract

In the title compound, [Zn(C14H8O5)(C15H11N3)]n, both the ZnII ion and the oxydibenzoate ligand are located on a twofold rotation axis. The ZnII centre is coordinated by three N atoms from a chelating 2,2′:6′,2′′-terpyridine ligand and two O atoms from two 2,2′-oxydibenzoate ligands, forming a distorted trigonal-bipyramidal coordination environment. Further coordination via the 2,2′-oxydibenzoate anions forms a one-dimensional coordination polymer extending parallel to [010]. Aromatic π–π stacking interactions are observed between adjacent terpyridine ligands with a centroid–centroid distance of 3.568 (2) Å.
