Abstract The reaction of [MoCl4(PPh3)2] with 2,4,6-i-Pr3C6H2SH (TIPTH) in CH2Cl2 followed by introduction of an excess of O2, yields the binuclear Mo(V) complex, [Mo2O4(2,4,6-i-Pr3C6H2S)2(PPh3)2]. An X-ray diffraction study of this complex revealed the presence of the common [Mo2O4]2+ core, with each Mo(V) center additionally coordinated to the phosphorus donor of a triphenylphosphine and to the sulfur
