The structure described by Pt3Cr is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Cr(1) is bonded to twelve equivalent Pt(1) atoms to form CrPt12 cuboctahedra that share corners with twelve equivalent Cr(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Cr4Pt8 cuboctahedra, faces with six equivalent Cr(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Cr4Pt8 cuboctahedra. Pt(1) is bonded to four equivalent Cr(1) and eight equivalent Pt(1) atoms to form distorted PtCr4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)Cr4Pt8 cuboctahedra, edges with eight equivalent Cr(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Cr4Pt8 cuboctahedra, faces with four equivalent Cr(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Cr4Pt8 cuboctahedra. is represented by the CIF file [CIF]
