Me 3 SiCH 2 )得到Cp*W(＝0)(＝S)R(la，R＝Me；lb，R＝Me 3 SiCH 2 )。类似地，Cp*Mo(=0)2(CH2SiMe3)得到Cp*Mo(=0)(=S)(CH2SiMe3)(2)。然而，在与 H2S 反应时，Cp* Mo (== 0) 2Me 生成对空气敏感的红色化合物，其特征为二硫化物 Cp* Mo (= 0)(2-82) ß，它很容易被氧化形成稳定的化合物 Cp* Mo (= 0)(j? 2-S20) Me (3)。详细报道了Cp*Mo(=0)(?j2-S2O)Me的晶体结构。该化合物在正交空间群 Pbca (No. 61) 中结晶，Z= 8、a= 25.134 (9)、b= 10.000 (6)、c= 11.009 (7) Á、V= 2767 A。所有非氢原子的各向异性细化和在计算位置包含氢原子收敛到残差^= 0.038 R2=0.045。
Me3SiCH2) gave Cp* W (= 0)(= S) R (la, R= Me; lb, R= Me3SiCH2). Similarly, Cp* Mo (= 0) 2 (CH2SiMe3) gave Cp* Mo (= 0)(= S)(CH2SiMe3)(2). However, on reaction with H2S, Cp* Mo (== 0) 2Me gave an air-sensitive red compound, characterized as the disulfide Cp* Mo (= 0)(2-82) ß, which is readily oxidized to form a stable compound, Cp* Mo (= 0)(j? 2-S20) Me (3). The crystal structure of Cp* Mo (= 0)(? j2-S20) Me is reported in detail. The compound crystallizes in the orthorhombic space group Pbca (No. 61) with Z= 8, a= 25.134 (9), b= 10.000 (6), and c= 11.009 (7) Á, and V= 2767 A. Anisotropic refinement of all non-hydrogen atoms and inclusion of hydrogen atoms at calculated positions converged to the residuals^= 0.038 and R2= 0.045.
