Ultra Violet and Visible Spectra of Some Divalent Transition Cupferrone Complexes

Abstract

The UV and visible absorption spectra of the ammonium salt of cupferrone and manganese, cobalt, nickel, copper and zinc divalent cupferrate complexes are investigated. The absorption bands observed are given and assigned on the basis of ligand field theory. In the UV absorption spectrum of the cupferrone metal complexes a characteristic shift in the maxima and minima appears. The effect of solvent on this shift was investigated. © 1974, Walter de Gruyter. All rights reserved.
