Abstract:
The mol-ecular structure of the mononuclear complex, [Cd(SCN)(2)(C(8)H(7)N(3))(2)], contains a Cd(II) atom in a distorted octa-hedral coordination defined by five N atoms from two bidentate chelate 2-(1H-pyrazol-3-yl)pyridine ligands and by one SCN(-) anion. The second SCN(-) anion provides its S atom for completion of the coordination sphere. The complex is linked to four others by N-H⋯N and N-H⋯S hydrogen-bonding inter-actions between the pyrazol N-H group and the terminal S and N atoms of neighbouring SCN(-) anions. This arrangement leads to the formation of sheets parallel to (100). Face-to-face π-π stacking inter-actions with shortest inter-planar distances of 3.805 (2) and 3.696 (2) Å help to consolidate the crystal packing.

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.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
