Materials Data on Lu2GaNi2 by Materials Project
Lu2Ni2Ga crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Lu is bonded in a 10-coordinate geometry to six equivalent Ni and four equivalent Ga atoms. There are two shorter (2.79 Å) and four longer (2.90 Å) Lu–Ni bond lengths. There are two shorter (3.11 Å) and two longer (3.16 Å) Lu–Ga bond lengths. Ni is bonded in a 9-coordinate geometry to six equivalent Lu, one Ni, and two equivalent Ga atoms. The Ni–Ni bond length is 2.43 Å. Both Ni–Ga bond lengths are 2.51 Å. Ga is bonded to eight equivalent Lu and four equivalent Ni atoms to form a mixture of face and edge-sharing GaLu8Ni4 cuboctahedra.
