Abstract: | Summary The reaction of excess nitrosyl chloride with vanadium tetrachloride under specific conditions furnishes the previously unreported compound VCl4, 2NOCl. The formation of a 1 2 adduct shows that vanadium (IV) can behave as a typical tetravalent metal in the MIVCl4-NOCl system. Spectroscopic measurements reveal both nitrosonium and hexachlorometallate ions in the addition compound and indicate structural analogy with (NO)2-TiCl6. The complex may thus be designated as dinitrosonium hexachlorovanadate, (NO)2VCl6. However, this compound is probably not purely ionic, since the relatively low frequency observed for the IR-absorption of the NO+ ion (2146 cm–1 compared with the normal range 2150 to 2400 cm–1) and the appreciable volatility of the compound suggest a significant degree of covalent bonding.
