The structure described by TmNiAl2 crystallizes in the orthorhombic Cmcm space group. Tm(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 Tm(1) and six equivalent Al(1) atoms. Al(1) is bonded in a 3-coordinate geometry to five equivalent Tm(1) and three equivalent Ni(1) atoms. is represented by the CIF file [CIF]
