Materials Data on TbAlGa by Materials Project
TbGaAl is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Tb is bonded to six equivalent Ga and six equivalent Al atoms to form a mixture of edge and face-sharing TbAl6Ga6 cuboctahedra. All Tb–Ga bond lengths are 3.15 Å. All Tb–Al bond lengths are 3.15 Å. Ga is bonded in a 9-coordinate geometry to six equivalent Tb and three equivalent Al atoms. All Ga–Al bond lengths are 2.57 Å. Al is bonded in a 3-coordinate geometry to six equivalent Tb and three equivalent Ga atoms.
