Crystal structure of dibenzyldimethylsilane

Crystal structure of dibenzyldimethylsilane

In the title compound, C16H20Si, 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—Cmethyl bonds [Si—C = 1.856 (1) and 1.853 (1) Å]. The Cbenzyl—Si—Cben...

Description
Summary:In the title compound, C16H20Si, 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—Cmethyl bonds [Si—C = 1.856 (1) and 1.853 (1) Å]. The Cbenzyl—Si—Cbenzyl 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.
