The material structure described by PtHg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pt(1) is bonded to twelve equivalent Hg(1) atoms to form PtHg12 cuboctahedra that share corners with twelve equivalent Pt(1)Hg12 cuboctahedra, edges with twenty-four equivalent Hg(1)Hg8Pt4 cuboctahedra, faces with six equivalent Pt(1)Hg12 cuboctahedra, and faces with twelve equivalent Hg(1)Hg8Pt4 cuboctahedra. Hg(1) is bonded to four equivalent Pt(1) and eight equivalent Hg(1) atoms to form HgHg8Pt4 cuboctahedra that share corners with twelve equivalent Hg(1)Hg8Pt4 cuboctahedra, edges with eight equivalent Pt(1)Hg12 cuboctahedra, edges with sixteen equivalent Hg(1)Hg8Pt4 cuboctahedra, faces with four equivalent Pt(1)Hg12 cuboctahedra, and faces with fourteen equivalent Hg(1)Hg8Pt4 cuboctahedra. is represented by the CIF file [CIF]
