of the bis(dibutyltin) complex of 1,2,4,5-benzenetetrathiolate (btt) with 2 equiv of [Cp*Co(CO)I 2]. Mononuclear complexes are also obtained from 1,2,4,5-tetrakis(isopropylthio)benzene ( 2) and sodium in pyridine, from benzo[1,2- d;4,5- d ']bis(1,3-dithiolane-2,6-dione) ( 3) and ( t )BuOK in tetrahydrofuran, or from benzo[ d]-1,3-dithiolane-2-one ( 7) and ( t )BuOK to afford respectively 4a, 4b, and
双核Cp * Co二硫代烯烃配合物[Cp * Co(btt)CoCp *](1)是由1,2,4,5-苯四硫醇盐(btt)的双(二丁基锡)配合物与2反应制得的当量为[Cp * Co(CO)I 2]。也可以从1,2,4,5-四(异丙硫基)苯(2)和吡啶中的钠,从苯并[1,2-d; 4,5-d']双(1,3-二硫杂环戊烷)获得单核配合物-(2,6-dione)(3)和(t)BuOK在四氢呋喃中,或从苯并[d] -1,3-二硫杂环戊烷-2-one(7)和(t)BuOK分别得到4a,4b和[Cp * Co(bdt)](6),而[Cp * Co(dmit)](8)是通过文献方法获得的。确定了双核复合物1和单核复合物4a和6的X射线结构。它们均以Cp *为特征。。。btt面对面的分子间相互作用,导致周期性的4倍对称性基序。在CH 2Cl 2中进行的[Cp * Co(dithiolene)]配合物的循环伏
