Possible explanation of transformation of hydrogen vacancies to metal phase nuclei is suggested: new vacancies are more likely to appear near the first one compared to remote places. Using density functional theory method we calculated the electronic structure of stoichiometric a-AlH3 and a-AlH3 with a hydrogen atom removed from a regular lattice site with a vacancy in place of it.
