title: Triclinic polymorph of bis-(triphenyl-sil-yl) oxide toluene disolvate.
abstract: A new polymorph of the title compound, C(36)H(30)OSi(2)·2C(7)H(8), is reported, which is triclinic (P-1) instead of possessing the previously reported rhombohedral symmetry [Hönle et al. (1990). Acta Cryst. C46, 1982-1984]. Each of the -SiPh(3) units are related by the inversion center. The Si-O-Si moiety is linear with the O atom sitting on an inversion center, and the O-Si-(toluene ring centroid) angle is 3.69 (15)°. Each toluene mol-ecule is 5.622 (2) Å from the Si atom and has its closest contacts with the phenyl rings outside of the van der Waals radii.
