Abstract:
The asymmetric unit of the title compound, [Nd(C(9)H(3)O(6))(C(2)H(6)OS)(2)](n), contains one Nd(3+) ion, one benzene-1,3,5-tricarb-oxy-lic ligand and two coordinating dimethyl sulfoxide mol-ecules. The Nd(3+) ion is coordinated by six O atoms from four carboxyl-ate groups of the benzene-1,3,5-tricarboxyl-ate ligands and two O atoms from two dimethyl sulfoxide mol-ecules. The metal-organic cluster formed upon symmetry expansion of the asymmetric unit consists of two metal atoms and four benzene-1,3,5-tricarboxyl-ate groups, creating a paddle-wheel-type building block arrangement. The remaining coordination sites are occupied by additional benzene-1,3,5-tricarboxyl-ate groups and dimethyl sulfoxide mol-ecules, forming a three-dimensional polymeric rare earth metal-organic framework structure.

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.
