Fang-Wei and Z.-M. Mei

Abstract: In the title compound, [Co(C₈H₄O₄)(C₁₈H₁₀N₄)(H₂O)]_n, the Co^II atom is six-coordinated by three O atoms from two benzene-1,4-dicarboxylate (1,4-BDC) dianions (one bidentate and one monodentate), one water molecule and two N atoms from a bidentate dipyrido[3,2-a:2',3'-c]phenazine ligand, resulting in a distorted cis-CoO₄N₂ octahedral geometry. The Co^II atoms are bridged by the 1,4-BDC ligands, forming a single-chain polymer structure. Both BDC ligands are centrosymmetric. Neighbouring chains interact through - interactions [minimum centroid-centroid separation = 3.459 (2) Å] and O-HO hydrogen bonds.
