Dy3Hg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Dy(1) is bonded to eight equivalent Dy(1) and four equivalent Hg(1) atoms to form distorted DyDy8Hg4 cuboctahedra that share corners with twelve equivalent Dy(1)Dy8Hg4 cuboctahedra, edges with eight equivalent Hg(1)Dy12 cuboctahedra, edges with sixteen equivalent Dy(1)Dy8Hg4 cuboctahedra, faces with four equivalent Hg(1)Dy12 cuboctahedra, and faces with fourteen equivalent Dy(1)Dy8Hg4 cuboctahedra. Hg(1) is bonded to twelve equivalent Dy(1) atoms to form HgDy12 cuboctahedra that share corners with twelve equivalent Hg(1)Dy12 cuboctahedra, edges with twenty-four equivalent Dy(1)Dy8Hg4 cuboctahedra, faces with six equivalent Hg(1)Dy12 cuboctahedra, and faces with twelve equivalent Dy(1)Dy8Hg4 cuboctahedra.
