The synthesis and characterization of azido and cyanato dithiocarbamato nitrosyl complexes of molybdenum : Reduction of coordinated azide in Azidobis(N,N-diethyldithiocarbamato)(dimethyl sulphoxide)nitrosylmolybdenum

Abstract

The new complexes [MoL(S₂CNR₂)₂(Me₂SO)NO] (R = Et, L = NCO^- or N₃^-; R = Me, L = NCO^-) and (R'₄N) [MO(NCO)₂(S₂CNR₂)₂NO] (R = R' = Et; R = Me, R' = Me or Et) have been isolated following the reactions of cis MO(S₂CNR_~)₂(NO)₂] with sodium azide and potassium cyanate. Use of ¹⁵N-labelled azide has confirmed that molybdenum bonded to a single nitrogen atom must be involved in the reduction of this ligand to ammonia and dinitrogen in strong acid.
