The first structurally characterised lead(II) antimony compound with a chemical bond between lead and antimony, [Pb(4)(SbSiiPr(3))(6)] (3), was obtained by the reaction of iPr(3)SiSb-(SiMe(3))(2) with PbCl(2) in Et(2)O at 0 degrees C. The Pb(4)Sb(6) cage structure can be described as a Pb(4)Sb(4) heterocube where two SbSiiPr(3) edges are replaced by (SbSiiPr(3))(2). The average Pb-Sb bond length is 297.7 pm. The heterocubane compounds PbESi-tBu(2)Ph (E = P, As) were obtained from the reactions of Pb{N(SiMe(3))(2)}(2) with tBu(2)PhSiEH(2).
首例结构明确的铅(II) 锑化合物中存在铅与锑之间的化学键，[Pb(4)(SbSiiPr(3))(6)]（3），是通过在 0 摄氏度下用 Et(2)O 将 iPr(3)SiSb-(SiMe(3))(2)与 PbCl(2)反应得到的。Pb(4)Sb(6)笼状结构可以描述为 Pb(4)Sb(4)杂立方烷，其中两个 SbSiiPr(3)边缘被(SbSiiPr(3))(2)取代。平均 Pb-Sb 键长为 297.7 pm。杂立方烷化合物PbESi-tBu(2)Ph（E = P，As）是通过 Pb{N(SiMe(3))(2)}(2)与 tBu(2)PhSiEH(2)反应得到的。
