MgPu is beta-prime cadmium gold structured and crystallizes in the orthorhombic Pmma space group. Mg(1) is bonded to four equivalent Mg(1) and eight equivalent Pu(1) atoms to form MgPu8Mg4 cuboctahedra that share corners with eight equivalent Pu(1)Pu4Mg8 cuboctahedra, corners with ten equivalent Mg(1)Pu8Mg4 cuboctahedra, edges with six equivalent Mg(1)Pu8Mg4 cuboctahedra, edges with twelve equivalent Pu(1)Pu4Mg8 cuboctahedra, faces with eight equivalent Pu(1)Pu4Mg8 cuboctahedra, and faces with twelve equivalent Mg(1)Pu8Mg4 cuboctahedra. Pu(1) is bonded to eight equivalent Mg(1) and four equivalent Pu(1) atoms to form PuPu4Mg8 cuboctahedra that share corners with eight equivalent Mg(1)Pu8Mg4 cuboctahedra, corners with ten equivalent Pu(1)Pu4Mg8 cuboctahedra, edges with six equivalent Pu(1)Pu4Mg8 cuboctahedra, edges with twelve equivalent Mg(1)Pu8Mg4 cuboctahedra, faces with eight equivalent Mg(1)Pu8Mg4 cuboctahedra, and faces with twelve equivalent Pu(1)Pu4Mg8 cuboctahedra.
