Materials Data on MgGa3 by Materials Project

Abstract

MgGa3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg is bonded to twelve equivalent Ga atoms to form MgGa12 cuboctahedra that share corners with twelve equivalent MgGa12 cuboctahedra, edges with twenty-four equivalent GaMg4Ga8 cuboctahedra, faces with six equivalent MgGa12 cuboctahedra, and faces with twelve equivalent GaMg4Ga8 cuboctahedra. All Mg–Ga bond lengths are 2.98 Å. Ga is bonded to four equivalent Mg and eight equivalent Ga atoms to form distorted GaMg4Ga8 cuboctahedra that share corners with twelve equivalent GaMg4Ga8 cuboctahedra, edges with eight equivalent MgGa12 cuboctahedra, edges with sixteen equivalent GaMg4Ga8 cuboctahedra, faces with four equivalent MgGa12 cuboctahedra, and faces with fourteen equivalent GaMg4Ga8 cuboctahedra. All Ga–Ga bond lengths are 2.98 Å.
