The crystal structure described by UFe3B2 crystallizes in the hexagonal P6/mmm space group. U(1) is bonded in a 20-coordinate geometry to two equivalent U(1), twelve equivalent Fe(1), and six equivalent B(1) atoms. Fe(1) is bonded in a square co-planar geometry to four equivalent U(1) and four equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent U(1) and six equivalent Fe(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
