Bis(μ-biphenyl-2,2′-dicarboxylato)bis[aqua(2,2′-bipyridine)cadmium(II)]
Abstract
In the centrosymmetric dinuclear molecule of the title compound, [Cd2(C14H8O4)2(C10H8N2)2(H2O)2], the Cd2+ ion is coordinated by three O atoms from two different diphenyldicarboxylate (dpa) ligands (one O,O′-bidentate and one monodentate), a chelating bipyridine ligand and a water molecule, generating an extremely distorted trigonal-prismatic (or irregular) CdN2O4 coordination geometry for the metal ion. The bridging ligands generate an 18-membered ring, which is stabilized by two pairs of intramolecular O—H...O hydrogen bonds.
