Materials Data on ZnSiNi2 by Materials Project
Ni2ZnSi is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ni1+ is bonded to four equivalent Si4- atoms to form a mixture of distorted corner and edge-sharing NiSi4 tetrahedra. All Ni–Si bond lengths are 2.46 Å. Zn2+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. All Zn–Si bond lengths are 2.85 Å. Si4- is bonded in a 8-coordinate geometry to eight equivalent Ni1+ and six equivalent Zn2+ atoms.
