A tetranuclear copper(II) cluster: bis(μ‐4‐chlorobenzoato‐κ
The title compound, [Cu4(C7H4ClO2)4(C6H6NO)4], consists of isolated tetranuclear clusters, where the Cu2+ 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 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...Cu distances in the range 3.0266 (11)–3.5144 (13) Å.
