Abstract: In the title compound, [Cu₂(C₇H₅O₂)₄(C₁₀H₉N)₂], the paddle-wheel-type dinuclear complex molecule contains four bridging benzoate groups and two terminal 3-methylquinoline ligands. The asymmetric unit contains one and a half molecules with a total of three independent Cu atoms; there is an inversion center at the mid-point of the CuCu bond in one molecule. The octahedral coordination of each Cu atom, with four O atoms in the equatorial plane, is completed by an N atom of a 3-methylquinoline ligand [Cu-N = 2.190 (4)-2.203 (3) Å] and by another Cu atom [CuCu = 2.667 (1) and 2.6703 (7) Å]. The Cu atoms are all ca 0.22 Å out of the plane of the four bonded O atoms.
