Materials Data on CrNi3 by Materials Project

Abstract

Ni3Cr is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cr is bonded to twelve equivalent Ni atoms to form CrNi12 cuboctahedra that share corners with twelve equivalent CrNi12 cuboctahedra, edges with twenty-four equivalent NiCr4Ni8 cuboctahedra, faces with six equivalent CrNi12 cuboctahedra, and faces with twelve equivalent NiCr4Ni8 cuboctahedra. All Cr–Ni bond lengths are 2.51 Å. Ni is bonded to four equivalent Cr and eight equivalent Ni atoms to form NiCr4Ni8 cuboctahedra that share corners with twelve equivalent NiCr4Ni8 cuboctahedra, edges with eight equivalent CrNi12 cuboctahedra, edges with sixteen equivalent NiCr4Ni8 cuboctahedra, faces with four equivalent CrNi12 cuboctahedra, and faces with fourteen equivalent NiCr4Ni8 cuboctahedra. All Ni–Ni bond lengths are 2.51 Å.
