Abstract: In the title complex, [Co₂(C₁₄H₉O₄)₄(C₁₂H₈N₂)₂(H₂O)], each Co²⁺ cation is surrounded by two N atoms from a 1,10-phenanthroline (phen) ligand and four O atoms [one from a water molecule, one from a monodentate 2'-carboxybiphenyl-2-carboxylate (Hbpdc) ligand and two from two bridging Hbpdc ligands), thus forming a distorted CoO₄N₂ octahedron. The two Co²⁺ cations are bridged by two Hbpdc anions via their carboxylate groups to produce an eight-membered dinuclear ring. The Co centres are also bridged by a water molecule, this latter species lying on a twofold axis.
