TiH2 crystallizes in the tetragonal P4_2/mnm space group. Ti(1) is bonded to six equivalent H(1) atoms to form a mixture of edge and corner-sharing TiH6 octahedra. The corner-sharing octahedral tilt angles are 58°. H(1) is bonded in a trigonal planar geometry to three equivalent Ti(1) atoms.

The corner-sharing octahedral tilt angles are 58°. There are two shorter (1.82 Å) and four longer (1.84 Å) Ti(1)-H(1) bond lengths. H(1) is bonded in a trigonal planar geometry to three equivalent Ti(1) atoms.
