Materials Data on BaAlGe by Materials Project
BaAlGe crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ba is bonded to six equivalent Al and six equivalent Ge atoms to form a mixture of edge and face-sharing BaAl6Ge6 cuboctahedra. All Ba–Al bond lengths are 3.63 Å. All Ba–Ge bond lengths are 3.63 Å. Al is bonded in a distorted trigonal planar geometry to six equivalent Ba and three equivalent Ge atoms. All Al–Ge bond lengths are 2.53 Å. Ge is bonded in a distorted trigonal planar geometry to six equivalent Ba and three equivalent Al atoms.
