Abstract:
The three-dimensional polymeric title compound, {[Zn(C(9)H(4)N(2)O(4))]·H(2)O}(n), contains one crystallographically independent Zn(II) atom, one fully deprotonated 1H-benzimid-azole-5,6-dicarboxyl-ate (bdc) ligand and one uncoordinated water mol-ecule. The Zn(II) atom is four-coordinated by three O atoms and one N atom from the bdc ligands, giving a distorted tetra-hedral coordination geometry. The uncoordinated water mol-ecule is bound to the main structure through a strong bdc-water N-H⋯O hydrogen bond, and two much weaker water-bdc O-H⋯O inter-actions.

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.
