Description
Summary:In the title compound, C21H18Si, the coordination geometry around the Si atom is a slightly distorted tetrahedron with C—Si—C angles in the range 106.05 (11) to 110.58 (10) ° and Si–C bond lengths in the range 1.855 (2) to 1.883 (3) Å. The alkyne C—C bond length is 1.167 (4) Å. The dihedral angles between the three phenyl rings are 63.89 (7), 86.38 (7) and 70.51 (8)°. In the crystal, molecules interact only by van der Waals forces.
