Notes:
The two aromatic ring planes in phenyl 2-(trimethylsilylethynyl)phenyl ketone, C18H18OSi, form a dihedral angle of 67.16 (6)°. The Si atom lies 0.1330 (6) Å out of the plane formed by the disubstituted aromatic ring. The carbonyl unit is not coplanar with either aromatic ring, forming O—C—C—C torsion angles with magnitudes of 41.4 (3) and 33.3 (3)°. The triple bond length is 1.199 (3) Å and the C=O and C—Si bond distances are 1.218 (2) and 1.837 (2) Å, respectively. In 2-(trimethylsilylethynyl)benzaldehyde, C12H14OSi, the molecule lies on a crystallographic mirror plane. The triple bond has a length of 1.192 (3) Å and the C=O and C—Si bond distances are 1.196 (3) and 1.839 (3) Å, respectively.
