MgSc 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 Sc(1) atoms to form distorted MgMg4Sc8 cuboctahedra that share corners with eight equivalent Sc(1)Mg8Sc4 cuboctahedra, corners with ten equivalent Mg(1)Mg4Sc8 cuboctahedra, edges with six equivalent Mg(1)Mg4Sc8 cuboctahedra, edges with twelve equivalent Sc(1)Mg8Sc4 cuboctahedra, faces with eight equivalent Sc(1)Mg8Sc4 cuboctahedra, and faces with twelve equivalent Mg(1)Mg4Sc8 cuboctahedra. Sc(1) is bonded to eight equivalent Mg(1) and four equivalent Sc(1) atoms to form distorted ScMg8Sc4 cuboctahedra that share corners with eight equivalent Mg(1)Mg4Sc8 cuboctahedra, corners with ten equivalent Sc(1)Mg8Sc4 cuboctahedra, edges with six equivalent Sc(1)Mg8Sc4 cuboctahedra, edges with twelve equivalent Mg(1)Mg4Sc8 cuboctahedra, faces with eight equivalent Mg(1)Mg4Sc8 cuboctahedra, and faces with twelve equivalent Sc(1)Mg8Sc4 cuboctahedra.
