摘　　要：Co2 (CO) 8与二硫代双 (二异丙基硫代甲酰胺 )反应生成标题化合物 (SCo3 (CO) 7[SCN(i Pr) 2 ],Mr=5 4 9) .经X射线单晶结构分析表明晶体属于单斜晶系 ,P2 1/n空间群 ,a=11.4 5 2 (2 ) ,b =15 .0 2 8(3) ,c=12 .14 4 (2 ) ,α=90° ,β =92 .15 (3)° ,γ=90°,V =2 0 88.5 3 ,Z =4 ,μ =2 .5 88nm-1,Dc =1.74 7mg/m3 ,F(0 0 0 ) =10 96 该簇合物的分子骨架SCo3 为三角锥形 ,分子中有Co2 SCN(i-Pr) 2 四员环组件 。The title cluster was obtained by reaction of Co_2(CO)_8 with four thiuram (R_2NCSS)_2,and the crystal structure of the cluster was determined by X-ray single crystal diffraction method.The crystal of the cluster is monoclinic,belonging to the space group of P2_1/n and with the cell parameters:a=11.452 ?,b=15.028 ?,c=12.144 ?,α=90,β=92.15,=90.The structural analysis shows that the cluster contains framwork Co_3S with a thiocaraboxamido bidentate bridging ligand,which links to two cobalt atoms of the framwork by stand C atom to form a four member ring of Co_2SC.
