摘要
用Ru3(CO)12分别与三个含P、S杂原子的配体(C2H5SPS2)2(L1);(CH3SPS2)2(L2);(C6H5CH2SPS2)2(L3)反应得到了三个新的三核钌羰基硫簇合物Ru3(CO)10(μ-SC2H5)( )Ru3(CO)10(μ-SCH3)( )Ru3(CO)10(μ-SCH2C6H5)( ),对它们进行了元素分析以及IR、1HNMR谱学表征,同时用X-ray衍射法测定了簇合物 分子的晶体结构.X-ray晶体衍射分析证明: 属正交晶系,Pbca空间群,晶胞参数:a=17.380(4) ,b=12.766(3) ,c=17.451(4) ,α=β=γ=90°,V=3871.7(14) 3,Z=4,Dc=2.211mg/m3,R1=0.0221,WR2=0.0294.μ-SC2H5为边桥基配体.
Through the reaction of Ru_3(CO)_(12) with three ligands containing P and S atoms,(C_2H_5SPS_2)_2(L_1),(CH_3SPS_2)_2(L_2) and (C_6H_5CH_2SPS_2)_2(L_3),three new trinuclear ruthenium carbonyl clusters Ru_3(CO)_(10)(μ-SC_2H_5)(Ⅰ),Ru_3(CO)_(10)(μ-SCH_3)(Ⅱ) and Ru_3(CO)_(10)(μ-SCH_2C_6H_5)(Ⅲ) were prepared,and characterized by elementary analysis,IR and^1HNMR spectroscopy.The structure of the cluster Ⅰ was determined by X-ray single crystal diffraction.The X-ray structural analysis reveals that clusterⅠ belongs to the orthorhombic crystal system,Pbca space group with crystal parameters as follows:a=17.380(4),b=12.766(3),c=17.451(4),α=β=γ=90°,V=3871.7(14)~3,Z=4,Dc=2.211 mg/m^3,R_1=0.0221,WR_2=0.0294.μ-SC_2H_5 is a bridging bidentate ligand.
