Poly[di-μ-thiocyanato-κN:S;κS:N-bis-[2-(1H-1,2,3-triazol-1-yl-κN)pyra-zine]cadmium(II)]
Abstract:
In the title two-dimensional coordination polymer, [Cd(NCS)(2)(C(6)H(5)N(5))(2)](n), the Cd(II) ion (site symmetry ) is coordinated by two N atoms from two 2-(1H-1,2,3-triazol-1-yl)pyrazine ligands and two N and two S atoms from four thio-cyanate anions. The N-Cd bond lengths range from 2.323 (2) to 2.3655 (19) Å and the S-Cd bond length is 2.7117 (7) Å. The associated cisoid angles vary from 84.99 (7) to 95.01 (7)°, indicating that the Cd(II) ion assumes a distorted octa-hedral geometry. In the complex, each thio-cyanate anion functions as a bridging ligand, linking adjacent Cd(II) ions with a separation of 6.4919 (6) Å, resulting in the formation of a two-dimensional sheet structure in the bc plane.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

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.
