Materials Data on TmGa2Ni by Materials Project
TmNiGa2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 1-coordinate geometry to three equivalent Ni and ten equivalent Ga atoms. There are one shorter (2.82 Å) and two longer (2.98 Å) Tm–Ni bond lengths. There are a spread of Tm–Ga bond distances ranging from 2.96–3.23 Å. Ni is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent Ga atoms. There are two shorter (2.49 Å) and four longer (2.53 Å) Ni–Ga bond lengths. Ga is bonded in a 12-coordinate geometry to five equivalent Tm, three equivalent Ni, and two equivalent Ga atoms. There are one shorter (2.62 Å) and one longer (2.91 Å) Ga–Ga bond lengths.
