The 95Mo n.m.r. spectra of a series of compounds containing the fac-[MoVIO3] and cis-[MoVIO2] units are reported, together with those for the series [MoX2(R2NO)2](X = O or S; R = Et, PhCH2). Trends in the data are discussed. The stereochemistry in solution of certain of the cw-dioxo species is assigned by means of 13C n.m.r. spectroscopy. The crystal and molecular structure of [MoS2(Et2NO)2], 0-5C6H6 has been determined by X-ray crystallography. The steric and electronic requirements of the terminal sulfide ligands significantly affect the detailed coordination geometry relative to that observed for the dioxo analogue [MoO2(Et2NO)2]. Crystal data: A 10·162(2), b 11·836(2), c 14·437(2) Å, β 1..
