✦ Synopsis
The Fourier-transform Raman and IR spectra of cobalt dimethylglyoxime boron difluoride (cobaloxime boron diguoride) have been obtained, and vibrational assignments made. The assignments were consistent with the symmetry group DB for the molecular skeleton, although some variation from the vibrational activity of this point group for the methyl group vibrations was ascribed to the local symmetry group, C,,, and non-planarity about the nitrogen atoms. Raman and IR spectra of nickel dimethylglyoxime were recorded and used for comparison purposes to aid the assignment of the cobaloxime boron difluoride bands. Cobalt dimethylglyoxime boron difluotide and other cobaloxime-based structures have been proposed for use as chain-transfer catalysts in free-radical polymerization chemistry.
