The material described by CrB is delta Molybdenum Boride structured and crystallizes in the tetragonal I4_1/amd space group. Cr(1) is bonded in a 7-coordinate geometry to seven equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to seven equivalent Cr(1) and two equivalent B(1) atoms. is represented by the CIF card [CIF]
