The crystal structure described by Pt3Hg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Pt(1) is bonded to eight equivalent Pt(1) and four equivalent Hg(1) atoms to form PtHg4Pt8 cuboctahedra that share corners with twelve equivalent Pt(1)Hg4Pt8 cuboctahedra, edges with eight equivalent Hg(1)Pt12 cuboctahedra, edges with sixteen equivalent Pt(1)Hg4Pt8 cuboctahedra, faces with four equivalent Hg(1)Pt12 cuboctahedra, and faces with fourteen equivalent Pt(1)Hg4Pt8 cuboctahedra. Hg(1) is bonded to twelve equivalent Pt(1) atoms to form HgPt12 cuboctahedra that share corners with twelve equivalent Hg(1)Pt12 cuboctahedra, edges with twenty-four equivalent Pt(1)Hg4Pt8 cuboctahedra, faces with six equivalent Hg(1)Pt12 cuboctahedra, and faces with twelve equivalent Pt(1)Hg4Pt8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
