Heterocyclic base adducts of salicylaldehyde N(4)- cyclohexylthiosemicarbazone(H2L) copper(II) complexes have been synthesized
and characterized. I.r., electronic and e.s.r. spectra of the complexes, as well as i.r., electronic and 1H- and 13C-n.m.r.
spectra of the thiosemicarbazone have been obtained. Based on e.s.r. studies, all possible parameters have been calculated.
The g values, calculated for all the complexes in frozen solution, indicate the presence of the unpaired electron in the dx2−y2
orbital. The metal–ligand bonding parameters evaluated showed strong in-plane σ- and in-plane π-bonding. The magnetic and
spectroscopic data indicate a square-planar geometry for the four-coordinate and a distorted square-pyramidal structure for
the five-coordinate complexes. From cyclic voltammetric data quasireversible copper(II)/copper(I) couples are observed for
the complexes.
