Fe(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to six equivalent U(1) and four equivalent Fe(1) atoms.
UFeSi crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 9-coordinate geometry to four equivalent Fe(1) and six equivalent Si(1) atoms. There are a spread of U(1)-Fe(1) bond distances ranging from 2.74-2.88 Å. There are a spread of U(1)-Si(1) bond distances ranging from 2.95-3.13 Å. Fe(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Si(1) atoms. There are two shorter (2.41 Å) and two longer (2.44 Å) Fe(1)-Si(1) bond lengths. Si(1) is bonded in a 10-coordinate geometry to six equivalent U(1) and four equivalent Fe(1) atoms.
