The material structure described by MgGa2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Mg(1) is bonded to four equivalent O(1) atoms to form MgO4 tetrahedra that share corners with twelve equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Ga(1) is bonded to six equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Mg(1)O4 tetrahedra and edges with six equivalent Ga(1)O6 octahedra. O(1) is bonded to one Mg(1) and three equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing OMgGa3 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
