Notes:
The infrared spectra (3500-30 cm-1) of solid hexa-substituted P-hexamethylcyclotriborophosphanes [(CH3)2PBX2]3 where X = F, Cl, Br, I and CH3 and some corresponding B-monosubstituted and disubstituted species have been recorded. The Raman spectra (3500-10 cm-1) of the corresponding solids have also been investigated. The vibrational spectra of the hexa-substituted compounds could best be interpreted on the basis of C3ν molecular symmetry. The observed intermolecular vibrations for these solids indicate little factor group effects. The vibrational spectra of the corresponding B-monosubstituted compounds were very similar to those for the parent molecules with the addition of three ‘new’ B-X motions. The molecular symmetries are discussed in relation to a recent nuclear magnetic resonance study.
