The crystal structure described by YCoAl2 crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 1-coordinate geometry to three equivalent Co(1) and ten equivalent Al(1) atoms. Co(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 11-coordinate geometry to five equivalent Y(1), three equivalent Co(1), and three equivalent Al(1) atoms. is represented by the CIF card [CIF]
