2,2-Bis[3,5-bis-(di-methyl-amino)-phen-yl]-1,1,1,3,3,3-hexa-methyl-tris-ilane.

The title compound, C(26)H(48)N(4)Si(3), was synthesized by the reaction of 2,2-di-chloro-tris-ilane with 3,5-bis-(di-methyl-amino)-phenyl-lithium. In the mol-ecule, the dihedral angle between the benzene rings is 57.57†(7)° and the Si-Si-Si bond angle is 110.08†(2)°. In the crystal, mol-ecules are linked via an SiC-H⋯π(ar-yl) inter-action, forming a chain along the c-axis direction.
