Low temperature structure of and hydrogen bonding in AsD3

Abstract: The hydrogen compounds of the lighter Group V elements PnH3 (Pn = N, P, As) have been important starting materials for industrial processes for many decades, with phosphine and arsine (PH3 and AsH3) being important for the production of semiconductor materials. The crystal structures of PH3 and AsH3 are unknown. They are, however, of interest as we have shown in previous experiments, that they exhibit polymorphism with at least two (from powder X-ray diffraction) or possibly three (differential scanning calorimetry) different crystallographic phases. As in the series from NH3, PH3, AsH3, to SbH3, the strength of the hydrogen bonds decreases, while the significance of dipole-dipole interactions and van der Waals interactions increases, their structural elucidation is of fundamental interest. Within this experiment we will elucidate the crystal structure of the high- and low temperature polymorphs on the basis of neutron powder diffraction.
