摘要： 通过(μ-BrMgS)(μ-n-C4H9S)Fe2(CO)6与CH2=CH(这里有图片19900811-832-1.GIF)OCH3共轭加成及中间物的醇解反应先制得(μ-n-C4H9S)(μ-CH3O(这里有图片19900811-832-1.GIF)CH2CH2S)Fe2(CO)6,然后进一步将它同PPh3反应制得标题配合物,该簇合物晶体属C2/c空间群,α=30.892(4)Å,b=12.454(2)Å,c=25.725(4)Å;β=91.46(1)°,Z=8;Dc=1.284g/cm3;R=0.060,其簇核由2个铁原子和2个硫原子构成蝶式结构,2个三苯膦配体处于铁—铁变键反位,2个桥硫原子上的取代基团均以e键与硫原子相连。

Abstract: Reaction of triphenylphosphine with(μ-n-C4H9S)(μ-CH3OCH2CH2S)Fe2(CO)6,whichwas prepared from a conjugated addition reaction of(μ-BrMgS)(μ-n-C4H9S)Fe2(CO)6 with,CH2=CHOCH3 followed by an alcoholysis process,gave the title complex of (μ-n-C4H9S)·(μ-CH3OCH2CH2S).The crystals of the title complex are monoclinic, spacegroup C2/c,with α=30.892(4)Å,b=12.454(2)Å,c=25.725(4)Å;β=91.46(1)°,V=9893.7Å3;Z=8;Dc=1.284g/cm3;R=0.060. The cluster core of this complex consists of twoiron and two sulfur atoms with a butterfly configuration. Two triphenyl phosphine ligands are trans to Fe-Fe bent bond. The substituents are attached to sulfur atoms by e-bonds.
