In this work PPh3 and PPh3S mixture Is used as the synthetic reagent. The general strategy of synthesizing the complexes of the [MoOSL) type with the [MoOS]2+ core from corresponding complexes with the [MoO2]2+ core by in situ oxoremoval·sulphide addition process. Presence of the oxothlo core In all the [MoOSL] complexes Is established by their reaction with KCN resulting In the formation of the CNS- species. All the complexes are characterized by various spectroscopic (NMR, IR, UV·VIs) techniques and also by cyclic voltammetry. All the complexes exhibit an lrrevenlble overall 2 electron reductive response probably by proton assisted loss of the sulphldo group leading to the formation of the corresponding [MoOL] complex.
