Materials Data on Ba5Ga5Sn by Materials Project
Ba5Ga5Sn crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. there are three inequivalent Ba sites. In the first Ba site, Ba is bonded in a 4-coordinate geometry to nine Ga and one Sn atom. There are three shorter (3.51 Å) and six longer (3.57 Å) Ba–Ga bond lengths. The Ba–Sn bond length is 3.64 Å. In the second Ba site, Ba is bonded in a 9-coordinate geometry to six Ga and three equivalent Sn atoms. There are three shorter (3.65 Å) and three longer (3.76 Å) Ba–Ga bond lengths. All Ba–Sn bond lengths are 4.15 Å. In the third Ba site, Ba is bonded to two equivalent Ga and three equivalent Sn atoms to form corner-sharing BaGa2Sn3 trigonal bipyramids. Both Ba–Ga bond lengths are 3.59 Å. All Ba–Sn bond lengths are 3.51 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a distorted q6 geometry to six Ba and four Ga atoms. There are two shorter (2.71 Å) and two longer (2.77 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded in a 10-coordinate geometry to seven Ba and three equivalent Ga atoms. Sn is bonded to eleven Ba atoms to form distorted face-sharing SnBa11 trigonal bipyramids.
