The material structure described by Hf2Fe3Si is Hexagonal Laves-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 12-coordinate geometry to nine equivalent Fe(1) and three equivalent Si(1) atoms. Fe(1) is bonded to six equivalent Hf(1), four equivalent Fe(1), and two equivalent Si(1) atoms to form FeHf6Fe4Si2 cuboctahedra that share corners with four equivalent Si(1)Hf6Fe6 cuboctahedra, corners with fourteen equivalent Fe(1)Hf6Fe4Si2 cuboctahedra, edges with six equivalent Fe(1)Hf6Fe4Si2 cuboctahedra, faces with six equivalent Si(1)Hf6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Hf6Fe4Si2 cuboctahedra. Si(1) is bonded to six equivalent Hf(1) and six equivalent Fe(1) atoms to form SiHf6Fe6 cuboctahedra that share corners with twelve equivalent Fe(1)Hf6Fe4Si2 cuboctahedra, edges with six equivalent Si(1)Hf6Fe6 cuboctahedra, faces with two equivalent Si(1)Hf6Fe6 cuboctahedra, and faces with eighteen equivalent Fe(1)Hf6Fe4Si2 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
