The material described by Mg3Tm is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to eight equivalent Mg(1) and four equivalent Tm(1) atoms to form MgTm4Mg8 cuboctahedra that share corners with twelve equivalent Mg(1)Tm4Mg8 cuboctahedra, edges with eight equivalent Tm(1)Mg12 cuboctahedra, edges with sixteen equivalent Mg(1)Tm4Mg8 cuboctahedra, faces with four equivalent Tm(1)Mg12 cuboctahedra, and faces with fourteen equivalent Mg(1)Tm4Mg8 cuboctahedra. Tm(1) is bonded to twelve equivalent Mg(1) atoms to form TmMg12 cuboctahedra that share corners with twelve equivalent Tm(1)Mg12 cuboctahedra, edges with twenty-four equivalent Mg(1)Tm4Mg8 cuboctahedra, faces with six equivalent Tm(1)Mg12 cuboctahedra, and faces with twelve equivalent Mg(1)Tm4Mg8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
