Materials Data on SrGaGe by Materials Project

Sr(GaGe) crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded to six equivalent Ge atoms to form distorted edge-sharing SrGe6 octahedra. All Sr–Ge bond lengths are 3.30 Å. In the second Sr site, Sr is bonded in a 6-coordinate geometry to six equivalent Ga atoms. All Sr–Ga bond lengths are 3.20 Å. Ga is bonded in a 6-coordinate geometry to three equivalent Sr and three equivalent Ge atoms. All Ga–Ge bond lengths are 2.58 Å. Ge is bonded in a 6-coordinate geometry to three equivalent Sr and three equivalent Ga atoms.

Materials Data on SrGaGe by Materials Project

Sr(GaGe) is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Sr is bonded to six equivalent Ga and six equivalent Ge atoms to form a mixture of edge and face-sharing SrGa6Ge6 cuboctahedra. All Sr–Ga bond lengths are 3.44 Å. All Sr–Ge bond lengths are 3.44 Å. Ga is bonded in a distorted trigonal planar geometry to six equivalent Sr and three equivalent Ge atoms. All Ga–Ge bond lengths are 2.51 Å. Ge is bonded in a 3-coordinate geometry to six equivalent Sr and three equivalent Ga atoms.
