Bis(μ-biphenyl-2,2'-dicarboxyl-ato)bis-[aqua-(2,2'-bipyridine)cadmium(II)]
Abstract:
In the centrosymmetric dinuclear mol-ecule of the title compound, [Cd(2)(C(14)H(8)O(4))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Cd(2+) ion is coordinated by three O atoms from two different diphenyl-dicarboxyl-ate (dpa) ligands (one O,O'-bidentate and one monodentate), a chelating bipyridine ligand and a water mol-ecule, generating an extremely distorted trigonal-prismatic (or irregular) CdN(2)O(4) coordination geometry for the metal ion. The bridging ligands generate an 18-membered ring, which is stabilized by two pairs of intra-molecular O-H⋯O hydrogen bonds.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
