New Bonding Mode for Cyanoacetylene - A Tungsten(II) Fluoride Carbonyl Complex in Which Cyanoacetylene Serves as a 4-Electron Donor Alkyne Ligand
The synthesis, characterization, and reactivity of a new tungsten(II) fluoride carbonyl complex in which cyanoacetylene serves as a four-electron donor alkyne ligand is reported. X-ray crystallography revealed that the complex exhibits unusual N=C-C=C-H...F-W hydrogen bonding which controls the solid state packing of this molecule.
