Abstract:
The asymmetric unit of the title compound, [Cu(C(13)H(20)N(2)O(2))(2)](NCS)(2), contains one half-dication, located on an inversion center, and one thio-cyanate anion. Each Cu(II) atom is four-coordinated by two phenolate O and two imine N atoms from two symmetry-related Schiff base 2-{[2-(isopropyl-aza-nium-yl)eth-yl]imino-meth-yl}-6-meth-oxy-phenolate (L) ligands in a distorted square-planar geometry. The ammonium groups are involved in the formation of N-H⋯O and N-H⋯N hydrogen bonds, which link one dication and two anions into an electroneutral cluster. When very weak Cu-N interactions with a distance of 2.910 (5) Å between the metal and the thiocyanate anions in apical positions are considered, the secondary coordination polyhedron is a very elongated CuN(4)O(2) octahedron.

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...
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.
