Materials Data on Cr3Ni by Materials Project

Abstract

Cr3Ni is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cr is bonded to eight equivalent Cr and four equivalent Ni atoms to form CrCr8Ni4 cuboctahedra that share corners with twelve equivalent CrCr8Ni4 cuboctahedra, edges with eight equivalent NiCr12 cuboctahedra, edges with sixteen equivalent CrCr8Ni4 cuboctahedra, faces with four equivalent NiCr12 cuboctahedra, and faces with fourteen equivalent CrCr8Ni4 cuboctahedra. All Cr–Cr bond lengths are 2.52 Å. All Cr–Ni bond lengths are 2.52 Å. Ni is bonded to twelve equivalent Cr atoms to form NiCr12 cuboctahedra that share corners with twelve equivalent NiCr12 cuboctahedra, edges with twenty-four equivalent CrCr8Ni4 cuboctahedra, faces with six equivalent NiCr12 cuboctahedra, and faces with twelve equivalent CrCr8Ni4 cuboctahedra.
