Conclusions

  1. 1.

    The IR and Raman spectra of o-, m-, and p-carbaphosphaboranes (CPB) and carbaarsaboranes (CAB), as well as the IR spectra of C-deuterated m-CPB and m-CAB, were obtained in the region of 250–4000 cm−1.

  2. 2.

    The positions and integral intensities of the IR bands corresponding to the valence vibrations of CH were measured.

  3. 3.

    The C-H bond of CPB and CAB, just as in carboranes, is capable of giving a hydrogen bond, the enthalpy of formation of which with dimethyl sulfoxide is ∼2–3 kcal/mole.
