2-巯甲基噻吩与[Mn2（CO）10]原子簇化合物反应生成[MnS（CO）3]4及结构表征

The compound[Mn2(CO)1o]reacts with 2-(Methylthio)thiophene (C5H6S2) while refluxing in xylene to afford a methylthio-tetramanganese product[MnS(CO)3]4, in which C5H6S2 is cleaved with loss of thiophene. The crystal structure of[MnS(CO)3]4 has been studied by direct method. Based on the 21 685 unique reflections collected using MoKα of X-ray radiation and a CCD-based detector, it is refined to an agreement index (R1) of 0.079 0. The cell is triclinic with dimensions: a=1.719 49 nm, b=1.959 2 nm, c=2.632 6 nm and α=79.733°,β=71.407°, γ=89.387°. There are 12 unit cells of[MnS(CO)3]4 in the cell, with space group P1.
