 Title    On an Octastannanediide R*6Sn8[Na(THF)2]2 and the Possible Existence of an Octastannane R*6Sn8 [ 1 ]  
 Abstract    The black, air and moisture sensitive octastannanediide R*6Sn8[Na(THF)2]2 (4) (R* = Si/Bu3) is prepared by reaction of Sn[N(SiM e3)2]2 with R*Na in rBuOMe at -78°C . Red brown octa­ stannane R*6Sn8 (5) is formed by thermolysis of the tristannacyclopropene R*4Sn3 in benzene at 100 °C. According to the result of the X-ray structural analysis, 4 contains a Sn8 cubane with six Sn atoms each connected with R* and two at the end o f a space diagonal connected with Na(THF)2. A preliminary X-ray structure analysis shows 5 to adopt the same Sn8 cubane structure as 4 with two bare Sn atoms at the end of a space diagonal.
