Conclusions
-
1.
The Raman and IR spectra of 1,10-dicarbaclosodecaborane and its C-dideutero derivative were obtained in various aggregated states.
-
2.
An assignment of the frequencies was proposed on the basis of the activity of the vibrations in the Raman and IR spectra, the values of the degree of depolarization of the Raman lines, and the contours of the bands in the IR spectra of the gases.
-
3.
The vibrations associated with B-H, for analogously constructed carboranes p-B10H10C2H2 and p-B8H8C2H2, have close frequencies, while the vibrations associated with C-H have different frequencies, evidently on account of the different coordination of the carbon atoms in these compounds.
-
4.
According to the data of the IR spectra, 1,10-dicarbaclosodecaborane forms a hydrogen bond with DMSO.
