Formation of a 1-zircona-2,5-disilacyclopent-3-yne: coordination of 1,4-disilabutatriene to zirconocene?
Alkyne under stress: a novel metallacycle containing one Zr atom, two Si atoms, and a C≡C bond has been prepared and its structure elucidated (Zr green, Si blue, C gray). According to X-ray data, spectral properties, and DFT calculations, the bonding situation in this compound is characterized as a 1-metalla-2,5-disilacyclopent-3-yne with a weak metal-triple-bond interaction.
