The structure described by MgHg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent Hg(1) atoms to form MgHg12 cuboctahedra that share corners with twelve equivalent Mg(1)Hg12 cuboctahedra, edges with twenty-four equivalent Hg(1)Mg4Hg8 cuboctahedra, faces with six equivalent Mg(1)Hg12 cuboctahedra, and faces with twelve equivalent Hg(1)Mg4Hg8 cuboctahedra. Hg(1) is bonded to four equivalent Mg(1) and eight equivalent Hg(1) atoms to form distorted HgMg4Hg8 cuboctahedra that share corners with twelve equivalent Hg(1)Mg4Hg8 cuboctahedra, edges with eight equivalent Mg(1)Hg12 cuboctahedra, edges with sixteen equivalent Hg(1)Mg4Hg8 cuboctahedra, faces with four equivalent Mg(1)Hg12 cuboctahedra, and faces with fourteen equivalent Hg(1)Mg4Hg8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
