Materials Data on HoAlGa by Materials Project
HoAlGa is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ho is bonded to six equivalent Ga and six equivalent Al atoms to form a mixture of edge and face-sharing HoAl6Ga6 cuboctahedra. All Ho–Ga bond lengths are 3.12 Å. All Ho–Al bond lengths are 3.12 Å. Ga is bonded in a 3-coordinate geometry to six equivalent Ho 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 Ho and three equivalent Ga atoms.
