The material structure described by UFe5Sn is Bergman Structure: Mg32(Al,Zn)49 Bergman-like structured and crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 19-coordinate geometry to three equivalent Fe(1), three equivalent Fe(2), three equivalent Fe(4), six equivalent Fe(3), and four equivalent Sn(1) atoms. There are four inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 11-coordinate geometry to three equivalent U(1), one Fe(2), two equivalent Fe(3), two equivalent Fe(4), and three equivalent Sn(1) atoms. In the second Fe site, Fe(2) is bonded in a 2-coordinate geometry to three equivalent U(1), one Fe(1), one Fe(4), four equivalent Fe(3), and one Sn(1) atom. In the third Fe site, Fe(3) is bonded to three equivalent U(1), one Fe(1), two equivalent Fe(2), two equivalent Fe(3), two equivalent Fe(4), and two equivalent Sn(1) atoms to form a mixture of distorted edge, face, and corner-sharing FeU3Fe7Sn2 cuboctahedra. In the fourth Fe site, Fe(4) is bonded to three equivalent U(1), one Fe(2), two equivalent Fe(1), four equivalent Fe(3), and two equivalent Sn(1) atoms to form a mixture of distorted edge, face, and corner-sharing FeU3Fe7Sn2 cuboctahedra. Sn(1) is bonded in a 14-coordinate geometry to four equivalent U(1), one Fe(2), two equivalent Fe(4), three equivalent Fe(1), and four equivalent Fe(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
