The material structure described by CeNiAl2 crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1) and ten equivalent Al(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 3-coordinate geometry to five equivalent Ce(1) and three equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
