MgPu3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent Pu(1) atoms to form MgPu12 cuboctahedra that share corners with six equivalent Mg(1)Pu12 cuboctahedra, corners with twelve equivalent Pu(1)Pu8Mg4 cuboctahedra, edges with eighteen equivalent Pu(1)Pu8Mg4 cuboctahedra, faces with eight equivalent Mg(1)Pu12 cuboctahedra, and faces with twelve equivalent Pu(1)Pu8Mg4 cuboctahedra. Pu(1) is bonded to four equivalent Mg(1) and eight equivalent Pu(1) atoms to form PuPu8Mg4 cuboctahedra that share corners with four equivalent Mg(1)Pu12 cuboctahedra, corners with fourteen equivalent Pu(1)Pu8Mg4 cuboctahedra, edges with six equivalent Mg(1)Pu12 cuboctahedra, edges with twelve equivalent Pu(1)Pu8Mg4 cuboctahedra, faces with four equivalent Mg(1)Pu12 cuboctahedra, and faces with sixteen equivalent Pu(1)Pu8Mg4 cuboctahedra.
