Tetra-μ-benzoato-bis[(6-methylquinoline)copper(II)]

In the title compound, [Cu-2(C7H5O2)(4)(C10H9N)(2)], the paddle-wheeltype dinuclear complex is constructed by four bridging benzoate groups and two terminal 6- methylquinoline ligands. The asymmetric unit contains one- half of the whole molecule, and there is an inversion center at the mid- point of the Cu center dot center dot center dot Cu bond. The octahedral coordination of each Cu atom, with four O atoms in the equatorial plane, is completed by the N atom of the 6- methylquinoline molecule [Cu-N = 2.212 ( 2) angstrom] and by another Cu atom [ Cu center dot center dot center dot Cu = 2.6939 ( 13) angstrom]. The Cu atom lies 0.234 angstrom out of the plane of the four O atoms. The molecular packing is stabilized by one intramolecular C-H center dot center dot center dot O as well as C-H center dot center dot center dot pi and pi-pi interactions.
