نویسندگان
چکیده
The title complex, [Cu(2)(C(16)H(10)NO(2))(4)(CH(3)OH)(2)], consists of centrosymmetric wheel-shaped dinuclear neutral mol-ecules in which each Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by four O atoms of carboxyl-ate groups from different ligands at the basal plane and an O atom of a methanol mol-ecule at the axial position. In the crystal, the dinuclear complex mol-ecules are linked into one-dimensional supra-molecular columns parallel to the b axis by O-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.7259 (11) Å].

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 monod...
