The crystal structure described by YAl is delta Molybdenum Boride-like structured and crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 7-coordinate geometry to seven equivalent Al(1) atoms. Al(1) is bonded in a 9-coordinate geometry to seven equivalent Y(1) and two equivalent Al(1) atoms. is represented by the CIF card [CIF]
