Ligand-field splittings in non-cubic complexes. Part III. Tetragonal copper(II)–oxygen systems

Abstract

The dd spectra of tetragonal copper(II)–oxygen systems are discussed. The position of the transition dz2dx2y2 in eight compounds can be accounted for in terms of σ-bonding and electrostatic effects. The other two transitions are less readily treated since they are affected by π-bonding. However, the d orbital splitting in Cu(HCO2)2,4H2O can be satisfactorily deduced from parameters obtained empirically by fitting the spectrum of Egyptian Blue CaCuSi4O10, where the bonding situation is similar. In- and out-of-plane π bonding parameters are calculated empirically for each compound and the results are compared with the anisotropic orbital reduction factors k and k.
