title: Diethyl 4,5-diphenyl-3,6-bis-(trimethyl-sil-yl)benzene-1,2-dicarboxyl-ate.
abstract: In the title compound, C(30)H(38)O(4)Si(2), the two phenyl rings are twisted away from the central benzene ring by 70.28 (8) and 67.42 (7)°. The two Si atoms attached to the benzene ring deviate in opposite directions from the ring plane by 0.258 (3) and 0.206 (3) Å, respectively. One ethyl group is disordered over two conformations in a 0.568 (5):0.432 (5) ratio. The crystal packing exhibits weak inter-molecular C-H⋯O inter-actions.
