Abstract: Possible models for the arrangement of hydrogen atoms in the sites of the cubic lattice of titanium oxyhydride TiO_yH_p with vacancies in the metallic and nonmetallic sublattices are considered for the first time. It has been established that interstitial H atoms in oxyhydrides occupy vacant octahedral sites 4(b) of the oxygen sublattice. No displacement of H atoms in tetrahedral sites 8(c) is observed.

Keywords: Titanium oxyhydride, Nonstoichiometry, Hydrogen placing, Simulation, Octahedral and tetrahedral sites.
