Materials Data on ErGa3 by Materials Project
ErGa3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Er is bonded to twelve equivalent Ga atoms to form ErGa12 cuboctahedra that share corners with twelve equivalent ErGa12 cuboctahedra, edges with twenty-four equivalent GaEr4Ga8 cuboctahedra, faces with six equivalent ErGa12 cuboctahedra, and faces with twelve equivalent GaEr4Ga8 cuboctahedra. All Er–Ga bond lengths are 3.01 Å. Ga is bonded to four equivalent Er and eight equivalent Ga atoms to form distorted GaEr4Ga8 cuboctahedra that share corners with twelve equivalent GaEr4Ga8 cuboctahedra, edges with eight equivalent ErGa12 cuboctahedra, edges with sixteen equivalent GaEr4Ga8 cuboctahedra, faces with four equivalent ErGa12 cuboctahedra, and faces with fourteen equivalent GaEr4Ga8 cuboctahedra. All Ga–Ga bond lengths are 3.01 Å.
