The compound described by MgCu6PbO8 crystallizes in the cubic Fm-3m space group. Mg(1) is bonded to twelve equivalent Cu(1) atoms to form MgCu12 cuboctahedra that share corners with twelve equivalent Mg(1)Cu12 cuboctahedra and edges with twenty-four equivalent O(1)Cu3Pb tetrahedra. Cu(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and four equivalent O(1) atoms. Pb(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. O(1) is bonded to three equivalent Cu(1) and one Pb(1) atom to form distorted OCu3Pb tetrahedra that share corners with ten equivalent O(1)Cu3Pb tetrahedra, edges with three equivalent Mg(1)Cu12 cuboctahedra, and edges with three equivalent O(1)Cu3Pb tetrahedra. is represented by the CIF file [CIF]
