Triphen-yl(prop-2-yn-1-yl)silane.

ABSTRACT: In the title compound, C(21)H(18)Si, the coordination geometry around the Si atom is a slightly distorted tetra-hedron 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, mol-ecules inter-act only by van der Waals forces.
