NaMg is beta-prime cadmium gold structured and crystallizes in the orthorhombic Pmma space group. Na(1) is bonded to four equivalent Na(1) and eight equivalent Mg(1) atoms to form NaNa4Mg8 cuboctahedra that share corners with eight equivalent Mg(1)Na8Mg4 cuboctahedra, corners with ten equivalent Na(1)Na4Mg8 cuboctahedra, edges with six equivalent Na(1)Na4Mg8 cuboctahedra, edges with twelve equivalent Mg(1)Na8Mg4 cuboctahedra, faces with eight equivalent Mg(1)Na8Mg4 cuboctahedra, and faces with twelve equivalent Na(1)Na4Mg8 cuboctahedra. Mg(1) is bonded to eight equivalent Na(1) and four equivalent Mg(1) atoms to form MgNa8Mg4 cuboctahedra that share corners with eight equivalent Na(1)Na4Mg8 cuboctahedra, corners with ten equivalent Mg(1)Na8Mg4 cuboctahedra, edges with six equivalent Mg(1)Na8Mg4 cuboctahedra, edges with twelve equivalent Na(1)Na4Mg8 cuboctahedra, faces with eight equivalent Na(1)Na4Mg8 cuboctahedra, and faces with twelve equivalent Mg(1)Na8Mg4 cuboctahedra.
