Abstract:
In the title polymer, [Cd(C(16)H(10)O(4))(C(10)H(8)N(2))(H(2)O)](n), the Cd(II) ion is in a strongly distorted octa-hedral geometry, being coordinated by two N atoms from a 2,2'-bipyridine ligand, three carboxylate O atoms from two symmetry-related trans-stilbene-4,4'-dicarboxyl-ate dianions and one water mol-ecule. The stilbene ligand lies on an inversion centre at the midpoint of the central C=C bond. This feature generates the polymeric structure: adjacent Cd(II) ions are bridged by trans-stilbene-4,4'-dicarboxyl-ate dianions, giving rise to a one-dimensional structure. The coordinated water mol-ecule is involved in interchain 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.
