The crystal structure described by CrCr2Nb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Nb(1) is bonded to twelve equivalent Cr(1) atoms to form NbCr12 cuboctahedra that share corners with twelve equivalent Nb(1)Cr12 cuboctahedra, edges with twenty-four equivalent Cr(1)Nb4Cr8 cuboctahedra, faces with six equivalent Nb(1)Cr12 cuboctahedra, and faces with twelve equivalent Cr(1)Nb4Cr8 cuboctahedra. Cr(1) is bonded to four equivalent Nb(1) and eight equivalent Cr(1) atoms to form CrNb4Cr8 cuboctahedra that share corners with twelve equivalent Cr(1)Nb4Cr8 cuboctahedra, edges with eight equivalent Nb(1)Cr12 cuboctahedra, edges with sixteen equivalent Cr(1)Nb4Cr8 cuboctahedra, faces with four equivalent Nb(1)Cr12 cuboctahedra, and faces with fourteen equivalent Cr(1)Nb4Cr8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
