and [Co(SC6F5)(TC-4,4)] (2a), which were structurally characterized. Use of more electron-releasing thiolates afforded the [Co(TC-n,m)] reduction product and the corresponding disulfide. The bent nitrosyl complexes [Co(NO)(TC-3,3)] (1b) and [Co(NO)(TC-4,4)] (2b) were synthesized from [Co(TC-n,m)] and NO and their structures were also determined. Compounds 1a and 1b have square-pyramidal geometry like
[Co(TC-n,m)] +与(Me4N)(SC6F5)的反应,其中(TC-n,m)是
对苯二酚,具有n和m个连接基亚甲基,产生
硫醇盐配合物[Co(SC6F5) (TC-3,3)](1a)和[Co(SC6F5)(TC-4,4)](2a)进行了结构表征。使用更多的释放电子的
硫醇盐得到[Co(TC-n,m)]还原产物和相应的二
硫化物。由[Co(TC-n,m)]合成弯曲的亚
硝酰基配合物[Co(NO)(TC-3,3)](1b)和[Co(NO)(TC-4,4)](2b)。还确定了NO及其结构。化合物1a和1b与所有其他在结构上表征的[MX(TC-3,3)]配合物一样,具有方锥体的几何形状。化合物2a和2b具有三角双锥体的立体
化学,以前很少用于Co(III)。尽管1a,1b和2a是顺磁性的,由于
金属和NO pi *轨道之间的强抗键pi相互作用,图2b是抗磁性的。在过量的NO存在下,[Co(TC-4,4)
