Abstract A solution of [ReOCl3(PPh3)2] in benzene reacts with solid (NH4)2WS4, in the presence of traces of H2O, to give [ReOCl(WS4)2]2−, isolated as its PPh4 (1) and NEt4 (2) salts. Both (1) and (2) exhibit ν(Re=O) at ca. 930, ν(Re=Cl) at ca. 330 ν(W=S)t at ca. 495 and ν(W–S–Re) bridging vibration at ca. 460cm−1. The FAB mass spectrum of (1) shows a peak for [ReO(WS4)2]+␣(m/z=826 amu) in the positive mode and that for PPh4[ReOCl(WS4)]− (m/z=889amu) in the negative mode, confirming the suggested composition. This is the second example of a d2 metal ion forming a tetrathiometalate complex and also the first example of an oxometal ion (excepting those of W and Mo) forming a molecular complex with tetrathio- tungstate or -molybdate ligands.
