The black, air and moisture sensitive octastannanediide R * 6 Sn 8 [Na(THF) 2 ] 2 (4) (R* = SitBu 3 ) is prepared by reaction of Sn[N(SiMe 3 ) 2 ] 2 with R*Na in tBuOMe at -78°C. Red brown octastannane R* 6 Sn 8 (5) is formed by thermolysis of the tristannacyclopropene R* 4 Sn 3 in benzene at 100 °C. According to the result of the X-ray structural analysis, 4 contains a Sn 8 cubane with six Sn atoms each connected with R* and two at the end of a space diagonal connected with Na(THF) 2 . A preliminary X-ray structure analysis shows 5 to adopt the same Sn 8 cubane structure as 4 with two bare Sn atoms at the end of a space diagonal.
