Gm. Kollegger et al., SYNTHESIS AND MOLECULAR-STRUCTURE OF IBISMUTHA-2,3,5,6,7-PENTASILABICYCLO[2.2.1]HEPTANE, Organometallics, 15(20), 1996, pp. 4337-4338
In the reaction between dichlorodimethylsilane and sodium potassium bi
smuthide, which was prepared from the elements in dimethoxyethane, the
previously unknown cage Bi-2(SiMe(2))(5) is formed. It was isolated b
y crystallization from heptane, and its molecular structure was confir
med by X-ray analysis.
