Synthetic, spectroscopic and structural investigations as well as theoretical calculations show that the reaction of the d(0), four-electron donor alkyne complex [{WCl4(PhC2Ph)}2] with the silylamines Me3SiNHR (R=CMe3, CHMe2, CH2Me, 2,6-CHMe2Ph) leads to d(2), two-electron donor alkyne complexes containing an organoimido ligand.
