Transition-metal nitrosyl compounds. Part VI. Mononitrosyltrichloromolybdenum, mononitrosyltrichlorotungsten, and some related derivatives

Abstract

Nitrosyl chloride reacts with Mo₂(CO)₈Cl₄ and W₂(CO)₈Cl₄ to give the new mononitrosyl derivatives tentatively formulated as [Mo(NO)Cl₃]_n and [W(NO)Cl₃]_n together with small amounts of [Mo(NO)₂Cl₂]_m and [W(NO)₂Cl₂]_m. [Mo(NO)Cl₃]_n reacts with triphenylphosphine, triphenylphosphine oxide, 2,2′-bipyridyl, or NaS₂CNR₂ to give the mononitrosyl derivatives Mo(NO)Cl₃(Ph₃PO)₂, Mo(NO)Cl₃(bipy), or Mo(NO)(S₂CNR₂)₃ which have been fully characterised.
