Abstract:
In the structure of the title compound, [Cu(C(14)H(11)N(3)OS)(C(5)H(5)N)], the Cu(II) atom exhibits a slightly distorted square-planar CuN(2)OS coordination polyhedron consisting of a phenyl O, an azomethine N and a thio-amide S atom from the tridentate thio-semicarbazonate dianion, and the N atom of a pyridine mol-ecule. The thio-semicarbazonate ligand exists in the thiol tautomeric form as an E isomer. Rotational disorder of the pyridine and phenyl rings in a 1:1 ratio of the respective components is observed. An extensive network of weak N-H⋯S, C-H⋯O, C-H⋯N and C-H⋯S hydrogen-bonding inter-actions consolidates the 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.
