Ti2H3 crystallizes in the tetragonal P4_2/mcm space group. Ti(1) is bonded in a 6-coordinate geometry to two equivalent H(2) and four equivalent H(1) atoms. There are two inequivalent H sites. In the first H site, H(2) is bonded to four equivalent Ti(1) atoms to form a mixture of corner and edge-sharing HTi4 tetrahedra. In the second H site, H(1) is bonded to four equivalent Ti(1) atoms to form a mixture of corner and edge-sharing HTi4 tetrahedra.
Ti2H3 crystallizes in the tetragonal P4_2/mcm space group. Ti(1) is bonded in a 6-coordinate geometry to two equivalent H(2) and four equivalent H(1) atoms. Both Ti(1)-H(2) bond lengths are 1.95 Å. All Ti(1)-H(1) bond lengths are 1.89 Å. There are two inequivalent H sites. In the first H site, H(2) is bonded to four equivalent Ti(1) atoms to form a mixture of corner and edge-sharing HTi4 tetrahedra. In the second H site, H(1) is bonded to four equivalent Ti(1) atoms to form a mixture of corner and edge-sharing HTi4 tetrahedra.
