The crystal structure described by UFe2B6 crystallizes in the orthorhombic Immm space group. U(1) is bonded in a 16-coordinate geometry to four equivalent B(1) and twelve equivalent B(2) atoms. Fe(1) is bonded in a 10-coordinate geometry to four equivalent B(1) and six equivalent B(2) atoms. There are two inequivalent B sites. In the first B site, B(2) is bonded in a 9-coordinate geometry to three equivalent U(1), three equivalent Fe(1), one B(1), and two equivalent B(2) atoms. In the second B site, B(1) is bonded in a 9-coordinate geometry to two equivalent U(1), four equivalent Fe(1), one B(1), and two equivalent B(2) atoms. is represented by the CIF file [CIF]
