The structure described by TmNiGa2 crystallizes in the monoclinic P2_1/m space group. Tm(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1) and ten equivalent Ga(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Ga(1) atoms. Ga(1) is bonded in a 5-coordinate geometry to five equivalent Tm(1) and three equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
