Abstract:
The asymmetric unit of the title two-dimensional coordination polymer, {[Cd(C(14)H(8)O(4))(C(14)H(14)N(4))]·0.15H(2)O}(n), is composed of one Cd(II) cation, one biphenyl-2,4'-dicarboxylate (bpdc) anion, one 1,4-bis(imidazol-1-ylmethyl)benzene (bix) ligand and 0.15 solvent water molecules. The coordination environment of the Cd(II) cation is defined by four carboxylate O atoms from two different bpdc anions in a chelating mode and two N atoms from two distinct bix ligands, constructing a distorted trigonal prism polyhedron. Two inversion-related Cd(II) cations are bridged together by two positionally disordered bpdc anions, forming a 22-membered ring with a Cd...Cd distance of 9.1966 (9) Å. These rings are then further linked by two bix ligands, extending into a two-dimensional layer along (102) with 6(3) topology.

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.
