The title compound, [Cu-4(C7H4ClO2)(4)(C6H6NO)(4)], consists of isolated tetranuclear clusters, where the Cu2+ cations are five- and sixfold coordinated y O atoms from the 4-chlorobenzoate anions and by pyridine N and methanolate O atoms from bidentate 2-pyridylmethanolate ligands. While three Cu atoms are six-coordinated by an NO5 donor set forming distorted octahedra, the fourth Cu atom is five-coordinated by an NO4 donor set forming a distorted tetragonal-pyramidal coordination around the Cu atom. The nucleus is a deformed cubane-like Cu4O4 structure, with Cu center dot center dot center dot Cu distances in the range 3.0266 (11)-3.5144 (13) angstrom.
