The title compound Fe_3(CO)_8(C_6H_5NC)(μ_3-S)_2 (Ⅰ) was synthesized bythe reaction of C_6H_5NCS with Fe_3(CO)_12 at room temperature. The crystal andmolecular structure of the title compound were determined by single ctystal diffratttionmethod- Crystal data: monoclinic, space group P2_1/C, a=12．718(4)A, b=26.164(10)A,c=l3.741(7)A, β=117.18(2) °, V=4067(2)A~3, Z=8, Dc=1．825 g/cm3. The structure wassolved by direct method and difference Fourier synthesis, and refined by full-matrix Leastsquares with anisotropic thermal paramaters, using 1990 observed reflections [Ⅰ＞3σ(Ⅰ)].The final residual factor was R＝0．076, Rw＝0．082. The substituted ligand (C_6H_5NC)in Fe_3(CO)_8(C_6H_5NC)(μ_3-S)_2 is connected to the Fe(3) atom of the distorted tetragonalpyramid Fe_3S_2 framework.
