Materials Data on Nb3Cr by Materials Project

Abstract

Nb3Cr is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Nb is bonded to eight equivalent Nb and four equivalent Cr atoms to form NbNb8Cr4 cuboctahedra that share corners with twelve equivalent NbNb8Cr4 cuboctahedra, edges with eight equivalent CrNb12 cuboctahedra, edges with sixteen equivalent NbNb8Cr4 cuboctahedra, faces with four equivalent CrNb12 cuboctahedra, and faces with fourteen equivalent NbNb8Cr4 cuboctahedra. All Nb–Nb bond lengths are 2.92 Å. All Nb–Cr bond lengths are 2.92 Å. Cr is bonded to twelve equivalent Nb atoms to form CrNb12 cuboctahedra that share corners with twelve equivalent CrNb12 cuboctahedra, edges with twenty-four equivalent NbNb8Cr4 cuboctahedra, faces with six equivalent CrNb12 cuboctahedra, and faces with twelve equivalent NbNb8Cr4 cuboctahedra.
