Materials Data on Ga3Ge by Materials Project

Ga3Ge 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 Ge atoms to form GaGa8Ge4 cuboctahedra that share corners with twelve equivalent GaGa8Ge4 cuboctahedra, edges with eight equivalent GeGa12 cuboctahedra, edges with sixteen equivalent GaGa8Ge4 cuboctahedra, faces with four equivalent GeGa12 cuboctahedra, and faces with fourteen equivalent GaGa8Ge4 cuboctahedra. All Ga–Ga bond lengths are 2.99 Å. All Ga–Ge bond lengths are 2.99 Å. Ge is bonded to twelve equivalent Ga atoms to form GeGa12 cuboctahedra that share corners with twelve equivalent GeGa12 cuboctahedra, edges with twenty-four equivalent GaGa8Ge4 cuboctahedra, faces with six equivalent GeGa12 cuboctahedra, and faces with twelve equivalent GaGa8Ge4 cuboctahedra.

Materials Data on Ga3Ge by Materials Project

Ga3Ge crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Ga sites. In the first Ga site, Ga is bonded to eight Ga and four equivalent Ge atoms to form distorted GaGa8Ge4 cuboctahedra that share corners with four equivalent GeGa12 cuboctahedra, corners with fourteen GaGa8Ge4 cuboctahedra, edges with six equivalent GeGa12 cuboctahedra, edges with twelve GaGa8Ge4 cuboctahedra, faces with four equivalent GeGa12 cuboctahedra, and faces with sixteen GaGa8Ge4 cuboctahedra. There are a spread of Ga–Ga bond distances ranging from 2.96–3.09 Å. There are two shorter (2.96 Å) and two longer (3.09 Å) Ga–Ge bond lengths. In the second Ga site, Ga is bonded to eight equivalent Ga and four equivalent Ge atoms to form distorted GaGa8Ge4 cuboctahedra that share corners with four equivalent GeGa12 cuboctahedra, corners with fourteen GaGa8Ge4 cuboctahedra, edges with six equivalent GeGa12 cuboctahedra, edges with twelve equivalent GaGa8Ge4 cuboctahedra, faces with four equivalent GeGa12 cuboctahedra, and faces with sixteen GaGa8Ge4 cuboctahedra. There are two shorter (2.96 Å) and two longer (3.07 Å) Ga–Ge bond lengths. Ge is bonded to twelve Ga atoms to form GeGa12 cuboctahedra that share corners with six equivalent GeGa12 cuboctahedra, corners with twelve GaGa8Ge4 cuboctahedra, edges with eighteen GaGa8Ge4 cuboctahedra, faces with eight equivalent GeGa12 cuboctahedra, and faces with twelve GaGa8Ge4 cuboctahedra.
