Triclinic Polymorph of Bis(triphenylsilyl) 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 (P1(-)) insteady of possessing the previously reported rhombohedral symmetry [Hoenle 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) deg. Each toluene molecule is 5.622 (2) Angstrom A from the Si atom and has its closest contacts with the phenyl rings outside of the van der Walls radii.
