The Organosilicon Derivatives of Sulphur, Selenium and Tellurium

The reactivity of all triorganosilyl triorganolead oxides is so great, in fact, that they explode in the presence of aluminium chloride or carboxylic acid halides, with the departure of the lead. 

Caution the mixed oxides of silicon with tin and lead are very toxic. The mixed oxides are prepared as shown in Eq. 3.148  

According to their X-ray diffraction patterns, compounds (R—Si—Si 5)4, have an adamantane structure [324].
