title: Crystal structure of di-benzyl-dimethyl-silane.
abstract: In the title compound, C16H20Si, a geometry different from an ideal tetra-hedron 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-Cmeth-yl bonds [Si-C = 1.856 (1) and 1.853 (1) Å]. The Cbenz-yl-Si-Cbenz-yl bond angle [C-Si-C = 107.60 (6)°] is decreased from the ideal tetra-hedral angle by 1.9°. These distortions can be explained easily by Bent's rule. In the crystal, mol-ecules inter-act only by van der Waals forces.
