Jl. Kiplinger et al., NEW BONDING MODE FOR CYANOACETYLENE - A TUNGSTEN(II) FLUORIDE CARBONYL COMPLEX IN WHICH CYANOACETYLENE SERVES AS A 4-ELECTRON DONOR ALKYNE LIGAND, Inorganic chemistry, 34(1), 1995, pp. 399-401
The synthesis, characterization, and reactivity of a new tungsten(II)
fluoride carbonyl complex in which cyanoacetylene serves as a four-ele
ctron donor alkyne ligand is reported. X-ray crystallography revealed
that the complex exhibits unusual N=C-C=C-H...F-W hydrogen bonding whi
ch controls the solid state packing of this molecule.
