ON THE DIOXIMINE COMPLEXES OF TRANSITION METALS. XCV. NEW IODO-AMINO-BIS-DIMETHYLGLYOXIMATO-COBALT(III)-NONELECTROLYTES

Abstract

New nonelectrolytic type chelate compounds of cobalt(III) with the general formula [Co(DH)₂IA)] DH-monodeprotonated dimethylglyoxime, A -different aromatic and heterocyclic amines and tertiary phosphines) were obtained by means of a substitution reaction from the diiodo-bis-dimethylglyoximato-cobaltiat and the corresponding amines and phosphines in alcoholic-aqueous media. The nonelectrolytes are sparingly soluble in water and soluble in some organic solvents, e.g. CHCl₃, DMFA, DMSO, etc. These derivatives were characterized by lR and electronic spectra, and in several cases by derivatographic measurements.
