摘要： 用[(C2H5)4N]2MoS4、FeCl3和HSCH2CH2SH在甲醇-甲醇钠溶液中反应,得到化合物{(C2H5)4N}3·{[(SCH2CH2S)MoS3]2Fe}晶体.用X射线衍射测定了簇合物的晶体结构.晶体属于单斜晶系,空间群Cc,晶胞参数:a=14.0030Å、b=18.3970Å、c=17.5705Å、β=96.458°、V=4497.6Å3、z=4.结构经最小二乘方法修正后偏离因子为0.052.以KBH4为还原剂,簇合物具有乙炔还原为乙烯的活性,与uw-45重组也显示乙炔还原为乙烯的活性.同时还对簇合物红外光谱、紫外可见光谱、1HNMR谱、磁性以及穆斯堡尔谱等性质进行了研究.

Abstract: The crystal of [(C2H5)4N]3{[(SCH2CH2S)MoSs]2Fe} was obtained by the reaction of [(C2H5)4N]2 MoS4, FeCls and ethane-1, 2-dithiol in MeOH-MeONa. The crystal structure of the compound was measured by X-ray.The crystal belongs to the monoclinic system, it crystallizes in space group Cc with a =14.0030Å, b=18.3970Å, c=17.5705Å, β = 96.458°, V=4497.6Å3 and z = 4. The structure was refined by least-squares. The value of Rwas 0.052. The compound possesses activity of acetylene reduction with KBH4 as reductant, it displays good activity of acetylene reduction with reconstitution of uw45. The characters of IRuv-visible, 1H NMR, EPR, Mossbauer spectra and magnetic susceptibility of the compound have been investigated.
