Materials Data on Hf4AlSi by Materials Project
Hf4AlSi is Khatyrkite-derived structured and crystallizes in the tetragonal I422 space group. The structure is three-dimensional. Hf is bonded in a 4-coordinate geometry to two equivalent Al and two equivalent Si atoms. Both Hf–Al bond lengths are 2.85 Å. Both Hf–Si bond lengths are 2.85 Å. Al is bonded in a distorted q6 geometry to eight equivalent Hf and two equivalent Si atoms. Both Al–Si bond lengths are 2.62 Å. Si is bonded in a distorted q6 geometry to eight equivalent Hf and two equivalent Al atoms.
