The material described by Mg3Zr is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to eight equivalent Mg(1) and four equivalent Zr(1) atoms to form MgMg8Zr4 cuboctahedra that share corners with four equivalent Zr(1)Mg12 cuboctahedra, corners with fourteen equivalent Mg(1)Mg8Zr4 cuboctahedra, edges with six equivalent Zr(1)Mg12 cuboctahedra, edges with twelve equivalent Mg(1)Mg8Zr4 cuboctahedra, faces with four equivalent Zr(1)Mg12 cuboctahedra, and faces with sixteen equivalent Mg(1)Mg8Zr4 cuboctahedra. Zr(1) is bonded to twelve equivalent Mg(1) atoms to form ZrMg12 cuboctahedra that share corners with six equivalent Zr(1)Mg12 cuboctahedra, corners with twelve equivalent Mg(1)Mg8Zr4 cuboctahedra, edges with eighteen equivalent Mg(1)Mg8Zr4 cuboctahedra, faces with eight equivalent Zr(1)Mg12 cuboctahedra, and faces with twelve equivalent Mg(1)Mg8Zr4 cuboctahedra. is represented by the CIF file [CIF]
