The great steric crowding in the trisilane 1 is revealed in the significantly lengthened SiSi, SiC, and SiI bond as well as in the large SiSiSi and SiCC bond angles. A linear correlation between the average number of bulky substitutents per Si atom and the length of the SiSi bond has made it possible to classify substituents according to their steric effect.
