Materials Data on Hf2SiH by Materials Project
Hf2SiH is I4/mcm-derived structured and crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Hf is bonded in a distorted L-shaped geometry to four equivalent Si and two equivalent H atoms. All Hf–Si bond lengths are 2.79 Å. Both Hf–H bond lengths are 2.03 Å. Si is bonded in a 10-coordinate geometry to eight equivalent Hf and two equivalent Si atoms. Both Si–Si bond lengths are 2.72 Å. H is bonded to four equivalent Hf atoms to form edge-sharing HHf4 tetrahedra.
