摘要
用Co2(CO)8与CH3CSNH2反应制得产物Ⅰ,又用Na2Fe(CO)4与Ⅰ反应制得产物Ⅱ(Ⅰ:Co3(μ3-S)(CO)7(CH3CSNH),Ⅱ:Co2Fe(μ3-S)(CO)7(CH3CSNH).通过元素分析。IR、UV、1HNMR、MS表征并用X射线衍射法测得Ⅱ的单晶结构.该簇合物属三斜晶系、PT空间群,晶胞参数:a=0.9203(1),b=1.1296(2),c=1.1425(2)nm;α=116.40°(2),β=101.92°(2),γ=92.58°(1);z=2,V=1.2162nm3,Dc=1.698cm3,μ=21.89cm-1.结构分析表明,Co2FeS构三角锥分子骨架,所有CO均为端基配体,S1为面桥基配体,CH3CSNH为双齿配体,与Co、Fe形成五元环结构.
The Compound ⅠCo3(μ3-S) (CO)7 (CH3CSNH) was prepared by reaction of Co2(CO)8 with CH3CSNH2. Subsequently it was proposed with Na2Fe(CO)4 to give the compound Ⅱ Co2Fe(μ3-S) (CO)7(CH3CSNH). The compound Ⅰand Ⅱ have been char-acterized by elemental analysis, IR、UV、HNMR and MS spectrometties. The single crystal X-ray diffration show that the compound Ⅰand Ⅱ are of triclinic, belong to space group PT and the cell parameters as following: a = 0. 920 3(1), b= 1. 129 6(2), c = 1. 142 5(2) nm; α= 116. 40°(1), β=101. 92°(2), γ= 92. 58°(1 ); z= 2, V= 1. 216 2 nm3, Dc= 1. 698 cm3, μ= 21. 89 cm-1. The results suggcst that two con1P0u11tls all contain tetrahedral frameworks,all carbonyls arc terminal ligands and CH3CSNH as bidentate, in which S is birdging ligand,links up two cobalt to form a fivc-member ring.
