Abstract
The crystal of the title compound, Si2C44H42, belongs to space group P21/c with cell dimensions of a = 11.8349(6), b = 8.5746(5), c = 18.6172(10)Å, β = 95.785(3)°. The final R1[I > 2σ(I)] value is 0.0489. The central conjugated system composed of phenyleneethynylene groups takes a linear, but non-planar structure. The molecule has a center of symmetry. The dihedral angle between the central phenyl ring and the flanking phenyl ring is 18.7(1)°. The two trimethylsilyl groups are located on opposite sides of the molecule with respect to the central part.
