Abstract

In the title compound, [Cu(2)(C(7)H(5)O(2))(4)(C(10)H(9)N)(2)], the paddle-wheel-type dinuclear complex mol-ecule contains four bridging benzoate groups and two terminal 3-methyl-quinoline ligands. The asymmetric unit contains one and a half mol-ecules with a total of three independent Cu atoms; there is an inversion center at the mid-point of the Cu⋯Cu bond in one molecule. The octa-hedral coordination of each Cu atom, with four O atoms in the equatorial plane, is completed by an N atom of a 3-methyl-quinoline ligand [Cu-N = 2.190 (4)-2.203 (3) Å] and by another Cu atom [Cu⋯Cu = 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.
