Materials Data on Hf(SiNi)2 by Materials Project

Hf(NiSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Hf4+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Hf–Si bond lengths are 2.89 Å. Ni2+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing NiSi4 tetrahedra. All Ni–Si bond lengths are 2.26 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Hf4+, four equivalent Ni2+, and one Si4- atom. The Si–Si bond length is 2.31 Å.
