摘要：

The complex [WI(CO)(S2CNC4H8)(η2-MeC2Me)2] reacts with an equimolar amount of Na[BPh4] in acetonitrile at room temperature to give the cationic bisbut-2-yne complex [W(CO)(NCMe)(S2CNC4H8)(η2-MeC2Me)2][BPh4] (1) by replacement of an iodide ligand by acetonitrile. The crystal structure of 1 has been determined and reveals a pseudo-octahedral geometry with the mid points of the two cis-but-2-yne ligands approximately coplanar with the sulphur atoms of the dithiocarbamate ligand. Carbon monoxide and acetonitrile occupy the axial sites. 13C NMR spectroscopy shows the two but-2-yne ligands in 1 donate a total of 6 electrons to the tungsten. Preliminary studies of the chemistry of 1 are also described. © 1990.
