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.
在标题化合物C₂₁H₁₈Si中，硅原子周围的配位几何形状为略微扭曲的四面体，C-Si-C键角在106.05 (11)°至110.58 (10)°范围内，Si-C键长在1.855 (2)至1.883 (3) Å范围内。炔烃C-C键长为1.167 (4) Å。三个苯环之间的二面角分别为63.89 (7)°、86.38 (7)°和70.51 (8)°。在晶体中，分子仅通过范德华力相互作用。
