Materials Data on Ga3Si by Materials Project

Ga3Si is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a body-centered cubic geometry to four equivalent Ga and four equivalent Si atoms. All Ga–Ga bond lengths are 2.87 Å. All Ga–Si bond lengths are 2.87 Å. In the second Ga site, Ga is bonded in a body-centered cubic geometry to eight equivalent Ga atoms. Si is bonded in a body-centered cubic geometry to eight equivalent Ga atoms.

Materials Data on Ga3Si by Materials Project

Ga3Si is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ga is bonded to eight equivalent Ga and four equivalent Si atoms to form GaGa8Si4 cuboctahedra that share corners with twelve equivalent GaGa8Si4 cuboctahedra, edges with eight equivalent SiGa12 cuboctahedra, edges with sixteen equivalent GaGa8Si4 cuboctahedra, faces with four equivalent SiGa12 cuboctahedra, and faces with fourteen equivalent GaGa8Si4 cuboctahedra. All Ga–Ga bond lengths are 2.92 Å. All Ga–Si bond lengths are 2.92 Å. Si is bonded to twelve equivalent Ga atoms to form SiGa12 cuboctahedra that share corners with twelve equivalent SiGa12 cuboctahedra, edges with twenty-four equivalent GaGa8Si4 cuboctahedra, faces with six equivalent SiGa12 cuboctahedra, and faces with twelve equivalent GaGa8Si4 cuboctahedra.

Materials Data on Ga3Si by Materials Project

Ga3Si crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ga is bonded to eight equivalent Ga and four equivalent Si atoms to form GaGa8Si4 cuboctahedra that share corners with four equivalent SiGa12 cuboctahedra, corners with fourteen equivalent GaGa8Si4 cuboctahedra, edges with six equivalent SiGa12 cuboctahedra, edges with twelve equivalent GaGa8Si4 cuboctahedra, faces with four equivalent SiGa12 cuboctahedra, and faces with sixteen equivalent GaGa8Si4 cuboctahedra. There are a spread of Ga–Ga bond distances ranging from 2.92–3.04 Å. There are two shorter (2.90 Å) and two longer (3.00 Å) Ga–Si bond lengths. Si is bonded to twelve equivalent Ga atoms to form SiGa12 cuboctahedra that share corners with six equivalent SiGa12 cuboctahedra, corners with twelve equivalent GaGa8Si4 cuboctahedra, edges with eighteen equivalent GaGa8Si4 cuboctahedra, faces with eight equivalent SiGa12 cuboctahedra, and faces with twelve equivalent GaGa8Si4 cuboctahedra.
