Crystal structure of di­benzyl­dimethyl­silane

In the title compound, C(16)H(20)Si, a geometry different from an ideal tetra­hedron can be observed at the Si atom. The bonds from Si to the benzylic C atoms [Si—C = 1.884 (1) and 1.883 (1) Å] are slightly elongated compared to the Si—C(meth­yl) bonds [Si—C = 1.856 (1) and 1.853 (1) Å]. The C(benz­yl)—Si—C(benz­yl) bond angle [C—Si—C = 107.60 (6)°] is decreased from the ideal tetra­hedral angle by 1.9°. These distortions can be explained easily by Bent’s rule. In the crystal, mol­ecules inter­act only by van der Waals forces.
