tert-Butoxy-triphenyl-silane.

The title compound, C(22)H(24)OSi or Ph(3)SiO(t)Bu, shows a distorted tetra-hedral coordination sphere around the Si atom. The C-O-Si angle is 135.97†(12)° and the O-Si distance is 1.6244†(13)†à . The mol-ecules are held together by weak inter-actions only. An H⋯H distance of 2.2924†(7)†à is found between aryl H atoms and is the shortest inter-molecular distance in the structure. With regard to the broad applicability of R(3)SiO structural motifs in all fields of chemistry, the mol-ecule demonstrates a common model system for silicon centers surrounded by sterically demanding substituents.
