Tetra - Benzoato-bis-[(6-methyl-quino-line)-copper(II)]

In the title compound, [Cu2(C7H5O2)4(C10H9N)2], the paddle-wheel-type dinuclear complex is constructed by four bridging benzoate groups and two terminal 6-methyl-quinoline ligands. The asymmetric unit contains one-half of the whole mol-ecule, and there is an inversion center at the mid-point of the Cu⋯Cu bond. The octa-hedral coordination of each Cu atom, with four O atoms in the equatorial plane, is completed by the N atom of the 6-methyl-quinoline mol-ecule [Cu - N = 2.212 (2) Å] and by another Cu atom [Cu⋯Cu = 2.6939 (13) Å]. The Cu atom lies 0.234 Å out of the plane of the four O atoms. The molecular packing is stabilized by one intramolecular C - H⋯O as well as C - H⋯π and π-π interactions.
