LuNiGa2 crystallizes in the orthorhombic Cmcm space group. Lu(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 Lu(1) and six equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to five equivalent Lu(1), three equivalent Ni(1), and two equivalent Ga(1) atoms.
LuNiGa2 crystallizes in the orthorhombic Cmcm space group. Lu(1) is bonded in a 13-coordinate geometry to three equivalent Ni(1) and ten equivalent Ga(1) atoms. There is one shorter (2.79 Å) and two longer (2.97 Å) Lu(1)-Ni(1) bond lengths. There are a spread of Lu(1)-Ga(1) bond distances ranging from 2.93-3.22 Å. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Ga(1) atoms. There are two shorter (2.50 Å) and four longer (2.53 Å) Ni(1)-Ga(1) bond lengths. Ga(1) is bonded in a 10-coordinate geometry to five equivalent Lu(1), three equivalent Ni(1), and two equivalent Ga(1) atoms. There is one shorter (2.60 Å) and one longer (2.83 Å) Ga(1)-Ga(1) bond length.
