1,1-Dimethyl-2,3,4,5-tetraphenyl-1-silacyclopentadiene crystallizes in the P21/c space group, Z = 8. The two molecules in the asymmetric unit mainly differ in the rotations of the phenyl groups with respect to the silacyclopentadiene ring, presumably as a result of crystal packing forces. The geometry of the silole ring in the title compound deviates considerably from that observed in 1,1-dimethyl-2,5-diphenyl-1-silacyclopentadiene. Mean bond distances and angles in the silole ring are SiC 1.868(3), CC 1.358(2), CC 1.511(2) Å, CSiC 92.7(1), SiCC 107.6(2), CCC 116.0(1)°.
