Abstract: The title compound, C₁₉H₂₃NSi₂, is a TMS-protected rigid-rod di-yne. It is useful as a model compound for organometallic species of which it is a precursor and, like them, exhibits -conjugation through the heteroaromatic linker unit in the backbone. The molecule is pseudo-linear, with a planar central quinoline group. Two C-HN short intermolecular contacts are found, with CN distances of 3.483  (5) and 3.671  (6)  Å. An intermolecular contact between an aromatic H atom and the CC triple bond is also observed.
