The material structure described by HfZr is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Hf(1) is bonded to six equivalent Hf(1) and six equivalent Zr(1) atoms to form HfHf6Zr6 cuboctahedra that share corners with eighteen equivalent Hf(1)Hf6Zr6 cuboctahedra, edges with six equivalent Hf(1)Hf6Zr6 cuboctahedra, edges with twelve equivalent Zr(1)Hf6Zr6 cuboctahedra, faces with eight equivalent Hf(1)Hf6Zr6 cuboctahedra, and faces with twelve equivalent Zr(1)Hf6Zr6 cuboctahedra. Zr(1) is bonded to six equivalent Hf(1) and six equivalent Zr(1) atoms to form ZrHf6Zr6 cuboctahedra that share corners with eighteen equivalent Zr(1)Hf6Zr6 cuboctahedra, edges with six equivalent Zr(1)Hf6Zr6 cuboctahedra, edges with twelve equivalent Hf(1)Hf6Zr6 cuboctahedra, faces with eight equivalent Zr(1)Hf6Zr6 cuboctahedra, and faces with twelve equivalent Hf(1)Hf6Zr6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
