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

New nonelectrolytic type chelate compounds of cobalt(III) with the general formula [Co(DHhIA) (DH monodeprotonated dimethylglyoxime, A - different aromatic and het­ erocyclic amines and tertiary phosphines) were obtained by means of a substitution reac­ tion 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. CHCb, DMFA, DMSO, etc. These derivatives were characterized by lR and electronic spectra, and in several cases by derivatographic measurements.
