catena-Poly[[(1,10-phenanthroline)cobalt]-μ-2,4′-oxydibenzoato]

Abstract

In the title compound, [Co(C14H8O5)(C12H8N2)]n, the CoII atom is six-coordinated in a distorted octahedral coordination geometry by four O atoms from two chelating carboxylate groups from different 2,4′-oxydibenzoate anions and by two N atoms from a 1,10-phenanthroline (phen) ligand. The two benzene rings of the 2,4′-oxydibenzoate ligand form a dihedral angle of 77.14 (16)°. Adjacent CoII atoms are bridged by 2,4′-oxydibenzoate anions to form a helical chain that propagates along the b-axis direction. Neighboring chains are further assembled by intermolecular π–π stacking interactions between inversion-related phen ligands [centroid-to-centroid distance = 4.0869 (8) Å] to form a two-dimensional supramolecular architecture.
