NaMg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Na(1) is bonded to twelve equivalent Mg(1) atoms to form NaMg12 cuboctahedra that share corners with twelve equivalent Na(1)Mg12 cuboctahedra, edges with twenty-four equivalent Mg(1)Na4Mg8 cuboctahedra, faces with six equivalent Na(1)Mg12 cuboctahedra, and faces with twelve equivalent Mg(1)Na4Mg8 cuboctahedra. Mg(1) is bonded to four equivalent Na(1) and eight equivalent Mg(1) atoms to form MgNa4Mg8 cuboctahedra that share corners with twelve equivalent Mg(1)Na4Mg8 cuboctahedra, edges with eight equivalent Na(1)Mg12 cuboctahedra, edges with sixteen equivalent Mg(1)Na4Mg8 cuboctahedra, faces with four equivalent Na(1)Mg12 cuboctahedra, and faces with fourteen equivalent Mg(1)Na4Mg8 cuboctahedra.
