The first structurally characterised lead(ii) antimony compound with a chemical bond between lead and antimony, [Pb4(SbSiiPr 3)6] (3), was obtained by the reaction of iPr 3SiSb-(SiMe3)2 with PbCl2 in Et 2O at 0 °C. The Pb4Sb6 cage structure can be described as a Pb4Sb4 heterocube where two SbSiiPr 3 edges are replaced by (SbSiiPr3)2. The average Pb-Sb bond length is 297.7 pm. The heterocubane compounds [PbESi-tBu2Ph]4 (E = P, As) were obtained from the reactions of Pb{N(SiMe3)2}2 with tBu 2PhSiEH2. The Royal Society of Chemistry 2010.
