The mol-ecule of the title compound, C(32)H(34)Si(2), is situated about a centre of symmetry. The whole diphenyl-ethene fragment is planar and the C(ar)-Si-C(3) group is rotated by ca 30° with respect to the plane of the benzene ring. The crystal structure is stabilized by some C-H⋯π contacts as well as van der Waals inter-actions.
