The structure described by Cr2B is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Cr(1) is bonded in a 4-coordinate geometry to four equivalent B(1) atoms. B(1) is bonded in a 10-coordinate geometry to eight equivalent Cr(1) and two equivalent B(1) atoms. is represented by the CIF file [CIF]
