Poly[[triaqua-(μ(3)-4-oxidopyridine-2,6-dicarboxyl-ato)europium(III)] monohydrate]
Abstract:
In the title coordination polymer, {[Eu(C(7)H(2)NO(5))(H(2)O)(3)]·H(2)O}(n), the Eu(III) atom is eight-coordinated by a tridentate 4-oxidopyridine-2,6-dicarboxyl-ate (hpc) trianion, two monodentate hpc anions and three water mol-ecules, forming a distorted bicapped trigonal-prismatic coordination geometry. The hpc ligands bridge adjacent Eu(III) ions, forming infinite double chains. Adjacent chains are further connected by hpc ligands into sheets. O-H⋯O hydrogen bonds then generate a three-dimensional supra-molecular framework.

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.
