The crystal structure described by PtHg is Tetraauricupride structured and crystallizes in the tetragonal P4/mmm space group. Pt(1) is bonded to four equivalent Pt(1) and eight equivalent Hg(1) atoms to form distorted PtHg8Pt4 cuboctahedra that share corners with twelve equivalent Pt(1)Hg8Pt4 cuboctahedra, edges with eight equivalent Pt(1)Hg8Pt4 cuboctahedra, edges with sixteen equivalent Hg(1)Hg4Pt8 cuboctahedra, faces with eight equivalent Hg(1)Hg4Pt8 cuboctahedra, and faces with ten equivalent Pt(1)Hg8Pt4 cuboctahedra. Hg(1) is bonded to eight equivalent Pt(1) and four equivalent Hg(1) atoms to form distorted HgHg4Pt8 cuboctahedra that share corners with twelve equivalent Hg(1)Hg4Pt8 cuboctahedra, edges with eight equivalent Hg(1)Hg4Pt8 cuboctahedra, edges with sixteen equivalent Pt(1)Hg8Pt4 cuboctahedra, faces with eight equivalent Pt(1)Hg8Pt4 cuboctahedra, and faces with ten equivalent Hg(1)Hg4Pt8 cuboctahedra. is represented by the CIF card [CIF]
