Photoluminescent Mo(IV) and W(IV) bis-dithiolene complexes with bidentate phosphonodithioato ligand derived from Lawesson’s reagent

An unusual oxo transfer from metal (Mo, W)-oxo bis(dithiolene) to a ligand derived from Lawesson’s reagent in situ via Wittig type rearrangement results photoluminescent trigonal prismatic Mo(W) bis(dithiolene) phosphonodithioate complex. ► Mo and W dithiolene phosphonodithioato complexes are structurally characterized. ► These complexes exhibit trigonal prismatic structure possessing {MS 6 } core. ► Phosphonodithioato ligands are derived in...
