Molecular structure of crystalline complex SbCl5 center dot Py was determined for the first time and the structure of the complex SbCl5 center dot AN was refined by means of single crystal X-ray diffraction analysis. It is shown that donor-acceptor Sb-N bond lengths for these complexes are equal within the experimental error. Quantum chemical calculations of the complexes in the gas phase reveal that the energies of the donor-acceptor bond Sb-N are 88 and 180 kJ mol(-1) for SbCl5 center dot AN and SbCl5 center dot Py, respectively. It is established that the length of the donor-acceptor bond Sb-N in the crystal cannot serve as a measure of its strength.
