The material structure described by HfFeSi crystallizes in the orthorhombic Pnma space group. Hf(1) is bonded in a 9-coordinate geometry to four equivalent Fe(1) and five equivalent Si(1) atoms. Fe(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent Hf(1) and four equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
