Abstract

The title compound, [Cu(4)(C(7)H(4)ClO(2))(4)(C(6)H(6)NO)(4)], consists of isolated tetranuclear clusters, where the Cu(2+) cations are five- and sixfold coordinated by 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 NO(5) donor set forming distorted octahedra, the fourth Cu atom is five-coordinated by an NO(4) donor set forming a distorted tetragonal-pyramidal coordination around the Cu atom. The nucleus is a deformed cubane-like Cu(4)O(4) structure, with Cu···Cu distances in the range 3.0266 (11)-3.5144 (13) Å.
