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.

The rational design and syntheses of metal–organic frameworks has been of increasing interest in the crystal engineering of coordination polymers owing to their ability to provide diverse assemblies with fascinating topological structures and material properties (Han et al, 2005; Xue et al.,2009)
Summary
R factor = 0.073; wR factor = 0.141; data-to-parameter ratio = 12.8. In the title compound, [Co(C14H8O5)(C12H8N2)]n, the Co atom is six-coordinated in a distorted octahedral coordination geometry by four O atoms from two chelating carboxylate groups from different 2,40 -oxydibenzoate anions and by two N atoms from a 1,10-phenanthroline (phen) ligand. The two benzene rings of the 2,40 -oxydibenzoate ligand form a dihedral angle of 77.14 (16). Adjacent CoII atoms are bridged by 2,40 oxydibenzoate anions to form a helical chain that propagates along the b-axis direction. Neighboring chains are further assembled by intermolecular – stacking interactions between inversion-related phen ligands [centroid-to-centroid distance = 4.0869 (8) Å] to form a two-dimensional supramolecular architecture.
