Tetra-?-benzoato-bis-[(quinoxaline)copper(II)].

ABSTRACT: The paddlewheel-type centrosymmetric dinuclear title complex, [Cu(2)(C(7)H(5)O(2))(4)(C(8)H(6)N(2))(2)], contains four bridging benzoate groups and two terminal quinoxaline ligands. The octa-hedral coordination around each Cu atom, with four O atoms in the equatorial plane, is completed by an N atom of a quinoxaline mol-ecule [Cu-N = 2.2465?(18)?Å] and by the second Cu atom [Cu?Cu = 2.668?(5)?Å]. The Cu atom is 0.216?Å out of the plane of the four O atoms.

The paddlewheel-type centrosymmetric dinuclear title complex, [Cu(2)(C(7)H(5)O(2))(4)(C(8)H(6)N(2))(2)], contains four bridging benzoate groups and two terminal quinoxaline ligands. The octa-hedral coordination around each Cu atom, with four O atoms in the equatorial plane, is completed by an N atom of a quinoxaline mol-ecule [Cu-N = 2.2465 (18) Å] and by the second Cu atom [Cu⋯Cu = 2.668 (5) Å]. The Cu atom is 0.216 Å out of the plane of the four O atoms. ...[more]
