Abstract:  In the case of Cr0₂X₂ chromyl compounds it was possible to demonstrate by methods of molecular spectroscopy that the Сr0₂⁺ group has features of an oxycation group and its individual characteristics depend on the type of bonds with the remaining X. This is clearly evident from the reaction mechanism of chromyl compounds with hydrocarbons, which is different for chromyl chloride and chromyl acetate. New data, concerning the physico-chemical properties of molybdenum(VI) complexes containing an Mo0₂⁺ group, were obtained. The following compounds were investigated: Mo0₂Cl₂, Mo0₂Br₂ and complexes with acetyl acetone, 8-hydroxyquinoline and tri-phenylarsenic oxide. On this basis, among other facts, the spectroscopic characteristics of the MoO₂²⁺ group were obtained. The results of investigations of compounds with the vanadyl group VO.t also corroborate the opinion that the basic structure and the mechanism of light absorption is closely related to that of the above mentioned oxycations.
