Bis(μ-2-phenyl-quinoline-4-carboxyl-ato)-κO,O':O;κO:O,O'-bis-[(2,2'-bipyridine-κN,N')(2-phenyl-quinoline-4-carboxyl-ato-κO,O')cadmium(II)]

The neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (μ-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monodentate, two bidentate. Weak inter-molecular π-π inter-actions [centroid-centroid distance = 3.712 (3) Å] help to establish the packing of the structure.
