Materials Data on Hf2Si by Materials Project
Hf2Si is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Hf is bonded in a 4-coordinate geometry to four equivalent Si atoms. All Hf–Si bond lengths are 2.80 Å. Si is bonded in a 10-coordinate geometry to eight equivalent Hf and two equivalent Si atoms. Both Si–Si bond lengths are 2.60 Å.
