Abstract

The complex formation of the disubstituted alkynes with cuprous halides has been investigated. No cuprous iodide-alkyne complexes have been observed. Many of the physical characteristics of the cuprous chloride-and cuprous bromide-alkyne crystalline complexes have been determined. These include the dissociation vapor pressures, the heats of dissociation, the compositions, their solubilities in excess ligand, and the densities and vapor pressures of their saturated solutions. In addition the vapor pressure lowering as a function of temperature for the saturated solution of the cuprous chloride 3-hexyne system has been investigated and compared with a theoretical model. A study of the vapor pressure lowering as a function of temperature for alkyne solutions of constant concentration for the cuprous chloride 2-butyne and cuprous chloride 2-pentyne systems suggests the presence of more than one complex species in solution. A preliminary investigation of the absorption spectra indicates that the cuprous halide-alkyne complexes are strongly absorbent in the infrared and the ultraviolet. The unit cell and space group of the cuprous chloride-2-butyne complex are given.
