Si[C6H4–4-SiMe2(CH2CH=CH2)]4 (7b) and ClSi[C6H4–4-SiC6H4–4-SiMe2(CH2CH=CH2)}3]3 (10a) in the solid state are reported. The crystal structures of both dendrimers are based on C–H···πCC (πCC = double bond of the CH=CH2 groups) and π–π interactions. The 3D network structure observed for 7b is composed of three crystallographically independent head-to-head stacking columns along the crystallographic b axis
