Mn3Hg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mn(1) is bonded to eight equivalent Mn(1) and four equivalent Hg(1) atoms to form distorted MnMn8Hg4 cuboctahedra that share corners with twelve equivalent Mn(1)Mn8Hg4 cuboctahedra, edges with eight equivalent Hg(1)Mn12 cuboctahedra, edges with sixteen equivalent Mn(1)Mn8Hg4 cuboctahedra, faces with four equivalent Hg(1)Mn12 cuboctahedra, and faces with fourteen equivalent Mn(1)Mn8Hg4 cuboctahedra. Hg(1) is bonded to twelve equivalent Mn(1) atoms to form HgMn12 cuboctahedra that share corners with twelve equivalent Hg(1)Mn12 cuboctahedra, edges with twenty-four equivalent Mn(1)Mn8Hg4 cuboctahedra, faces with six equivalent Hg(1)Mn12 cuboctahedra, and faces with twelve equivalent Mn(1)Mn8Hg4 cuboctahedra.
