The homobinuclear compound Mn2(CO)6(m-S2CPiPr3) has been prepared by the reaction of BrMn(CO)3(m-S2CPiPr3) with NaMn(CO)5 in refluxing THF, and its structure was determined by single-crystal X-ray diffraction. Crystallographic data: C16H21Mn2O6PS2, Mr = 514.30, triclinic, space group Pīwith a = 9.293(3), b = 9.443(3), c = 12.977(4) ? a = 83.633(5), b = 83.719(5), g = 73.399(5), V = 1081.1(6) ?, Z = 2, Dc = 1.580 g/cm3, m = 1.463 mm-1, F(000) = 524, the final R = 0.0330 and wR = 0.0729 for 2945 observed reflections with I > 2s(I). The crystal structure determination shows that the ligand can be described as a 2(S, S? chelate to one manganese and a 3(S, C, S? pseudoallyl to the other manganese bridging the MnMn bond asymmetrically.
