Abstract:
The asymmetric unit of the title crystal structure, [Cd(3)(NCS)(6)(C(7)H(6)N(4))(2)](n), contains two independent Cd(II) ions, one of which is located on a crystallographic inversion center. Each independent Cd(II) ion is in a slightly distorted octa-hedral coordination environment, but the disortion from ideally octa-hedral is greater in the environment of the Cd(II) ion on a general position. Both thio-cyanate ligands act as bridges connecting independent Cd(II) ions, and the 2-(pyrazol-1-yl)pyrazine ligands chelate one Cd(II) ion in a bidentate mode while the remaining N atom of the pyrazine ring coordinates to a symmetry-related Cd(II) ion, forming a two-dimensional structure parallel to (211).

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.
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,...
