5,5′-Bis­(tri­methyl­silyl­ethynyl)-2,2′-bi­pyridine

The title compound, 5,5′-bis­(tri­methyl­silyl­ethynyl)-2,2′-bi­pyridine, C₂₀H₂₄N₂Si₂, is a tri­methyl­silyl-protected dialkyne. It is a precursor in the preparation of platinum di-yne complexes and platinum poly-yne polymers. Such organic compounds are of interest because of the extended π-conjugation that occurs through the hetero-aromatic linker unit in the molecular backbone. Within the mol­ecule, the ­silyl-alkyne groups are essentially linear and the bi­pyridine unit is approximately planar with a dihedral angle of 5.3 (1)° between the planes.
