catena-Poly[[(dipyrido[3,2-a:2′,3′-c]phenazine)cobalt(II)]-μ-biphenyl-2,2′-dicarboxylato]

Abstract

In the title compound, [Co(C14H8O4)(C18H10N4)]n, the CoII atom is six-coordinated by four O atoms from two different biphenyl-2,2′-dicarboxylate ligands and two N atoms from the bidentate dipyrido[3,2-a:2′,3′-c]phenazine ligand in a distorted octahedral geometry. The CoII atoms are bridged by the biphenyl-2,2′-dicarboxylate ligands to form a one-dimensional chain structure. π–π interactions between neighbouring chains result in a two-dimensional supramolecular network (centroid-to-centroid separation = 3.381 Å).
