Materials Data on NbCr3 by Materials Project

Abstract

CrCr2Nb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Nb is bonded to twelve equivalent Cr atoms to form NbCr12 cuboctahedra that share corners with twelve equivalent NbCr12 cuboctahedra, edges with twenty-four equivalent CrNb4Cr8 cuboctahedra, faces with six equivalent NbCr12 cuboctahedra, and faces with twelve equivalent CrNb4Cr8 cuboctahedra. All Nb–Cr bond lengths are 2.69 Å. Cr is bonded to four equivalent Nb and eight equivalent Cr atoms to form CrNb4Cr8 cuboctahedra that share corners with twelve equivalent CrNb4Cr8 cuboctahedra, edges with eight equivalent NbCr12 cuboctahedra, edges with sixteen equivalent CrNb4Cr8 cuboctahedra, faces with four equivalent NbCr12 cuboctahedra, and faces with fourteen equivalent CrNb4Cr8 cuboctahedra. All Cr–Cr bond lengths are 2.69 Å.
