Abstract

The asymmetric unit of the title compound, [Co(HCO2)2(C14H12N2)(H2O)]·H2O, contains a mononuclear complex molecule hydrogen bonded to a lattice water molecule. The CoII cation is in a distorted octahedral coordination environment defined by the two N atoms of the 2,9-dimethyl-1,10-phenanthroline ligand and four O atoms. Two of these are from a chelating formate anion, one from a monodentate formate and the last from an aqua ligand. In the crystal, molecules are connected by O—H⋯O hydrogen bonds, forming double chains along [100] with the 2,9-dimethyl-1,10-phenanthroline ligands pointing outwards from each chain. These chains are further linked into layers parallel to (011) by inter-chain π–π stacking interactions with centroid–centroid distances of 3.61 (1) Å.
