In the title complex, [Cu(CH3CO2)(C12H8N2)2](CH3CO2)·7H2O, the central CuII ion is five coordinate, being bound to four N atoms from two 1,10-phenanthroline ligands and one O atom from an acetate anion in a strongly distorted square-pyramidal configuration. Hydrogen-bonded water molecules and an uncoordinated acetate anion form a two-dimensional polymeric structure parallel to (010). The cations are linked to this layer via O—H⋯O hydrogen bonds between one of the water molecules and the coordinated acetate anion.
