Trimeth­yl(triphenyl­meth­oxy)silane

In the title mol­ecule, C(22)H(24)OSi, the Si—O—C angle is 139.79 (11)°, the O—C—C angles of the triphenyl­meth­oxy group are in the range 106.13 (13)–109.22 (14)° and the O—Si—C angles of the trimethyl­sil­yloxy 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 triphenyl­methyl substituent are mutually nearly perpendicular, with dihedral angles in the range 80.49 (8)–81.53 (8)°. There are only weak inter­molecular van der Waals inter­actions in the crystal.
