The crystal structure described by CeMg 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 Ce(1) atoms to form MgCe8Mg4 cuboctahedra that share corners with eight equivalent Ce(1)Ce4Mg8 cuboctahedra, corners with ten equivalent Mg(1)Ce8Mg4 cuboctahedra, edges with six equivalent Mg(1)Ce8Mg4 cuboctahedra, edges with twelve equivalent Ce(1)Ce4Mg8 cuboctahedra, faces with eight equivalent Ce(1)Ce4Mg8 cuboctahedra, and faces with twelve equivalent Mg(1)Ce8Mg4 cuboctahedra.
