Synthesis and Crystal Strucutre of Fe3(CO)8(C6H5NC)(μ3-S)2
The title compound Fe_3(CO)_8(C_6H_5NC)(μ_3-S)_2 (Ⅰ) was synthesized by the reaction of C_6H_5NCS with Fe_3(CO)_12 at room temperature. The crystal and molecular structure of the title compound were determined by single ctystal diffraction method. Crystal data: monoclinic, space group P2_1/C, a=12.718(4)Å, b=26.164(10) Å, c=l3.741(7) Å, β=117.18(2) °, V=4067(2) Å3, Z=8, Dc=1.825 g/cm3. The structure was solved by direct method and difference Fourier synthesis, and refined by full-matrix Least-squares 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 tetra nal pyramid Fe_3S_2 framework.
