The crystal structure described by YIr3B2 crystallizes in the hexagonal P6/mmm space group. Y(1) is bonded in a 20-coordinate geometry to two equivalent Y(1), twelve equivalent Ir(1), and six equivalent B(1) atoms. Ir(1) is bonded in a distorted square co-planar geometry to four equivalent Y(1) and four equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to three equivalent Y(1) and six equivalent Ir(1) atoms. is represented by the CIF card [CIF]
