Abstract

In the title mol-ecule, C(22)H(24)OSi, the Si-O-C angle is 139.79 (11)°, the O-C-C angles of the triphenyl-meth-oxy group are in the range 106.13 (13)-109.22 (14)° and the O-Si-C angles of the trimethyl-sil-yloxy group are in the range 103.08 (10)-113.53 (10)°. In the crystal, face-to-face π-π interactions are observed between the phenyl rings [centroid separation = 4.194 (1) Å, interplanar spacing = 3.474 Å and centroid shift = 2.35 Å]. The three phenyl groups of the triphenyl-methyl substituent are mutually nearly perpendicular, with dihedral angles in the range 80.49 (8)-81.53 (8)°. There are only weak inter-molecular van der Waals inter-actions in the crystal.
