Abstract

In the title compound, [Cu(CHO2)(C12H8N2)2]CHO2·6H2O, the Cu atom is coordinated in a distorted trigonal-bipyramidal fashion by an O atom of the formate ligand and four N atoms of two phenanthroline ligands with Cu—O and Cu—N distances of 2.020 (3) and 1.978 (3)–2.177 (3) Å, respectively. Hydrogen bonding O—H⋯O between water molecules and between water anions as well as π–π interactions [centroid–centroid distances between phen rings = 3.38 (7) and 3.40 (5) Å] are responsible for the supramolecular assembly.
