the isolation of the homoleptic, tetrahedral osmium(IV) compounds OsR4(R = C6H4Me-o or C6H5). Thermally stable M (C6H11)4 compounds (M = Ru, Os, or Cr; C6H11= cyclohexyl) are obtained by the interaction of the Grignard reagent with Ru2(O2CMe)4Cl, Os2(O2CMe)4Cl2, and CrCl3(thf)3(thf = tetrahydrofuran) respectively. The structures of all five compounds have been determined by X-ray crystallography.
邻甲苯基溴化镁或AlPh 3(OEt 2)与四氧化的相互作用导致分离出均相的四面体((IV)化合物OsR 4(R = C 6 H 4 Me- o或C 6 H 5)。通过格氏试剂与Ru 2(O 2 CMe)4 Cl,Os 2的相互作用获得热稳定的M(C 6 H 11)4化合物(M = Ru,Os或Cr; C 6 H 11 =环己基)(O2 CMe) 4 Cl 2和CrCl 3(thf) 3(thf =四氢呋喃)。所有五种化合物的结构均已通过X射线晶体学测定。
