Addition of B2S3 to a methanolic solution of the MoVIO3L2− complex (L=N,N-bis(ethanoic acid)-1-amino-2- methylthio-ethane) results in the formation of two different monomeric oxosulfidomolybdate(VI) complexes, [MoO2SL]2− and [MoOS2L]2− as indicated by 1H, 13C, 17O and 95Mo NMR spectroscopy and by the reaction of these two sulfurated species with triphenylphosphine. The temperature dependences of the 1H NMR spectra indicate exchange processes for both sulfido complexes. Their redox properties are discussed and contrasted with those observed for the parent fac-trioxo molybdenum(VI) complex. The primary synthetic route to mixed oxosulfido [MoO3−nSnL]2− complexes described here can be extended to other aminodicarboxylic ligands like iminodiacetic acid.
