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 donor of a terminally ligated TIPT group. Crystal data for [Mo2O4(2,4,6-i-Pr3C6H2S)2]: orthorhombic space group Pccn, a = 29.772(4), b =22.193(4), c= 19.016(3) Å, V= 12564.6(11) Å3, Dcalc = 1.32 g cm-3, Z = 8. Structure solution and refinement based on 1279 reflections (Mo Koα, λ = 0.71073 Å, 2° ≤ 2θ ≤ 45°) converged at a conventional discrepancy value of 0.063.
