Fe3Ga is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to eight equivalent Fe(1) and four equivalent Ga(1) atoms to form FeGa4Fe8 cuboctahedra that share corners with twelve equivalent Fe(1)Ga4Fe8 cuboctahedra, edges with eight equivalent Ga(1)Fe12 cuboctahedra, edges with sixteen equivalent Fe(1)Ga4Fe8 cuboctahedra, faces with four equivalent Ga(1)Fe12 cuboctahedra, and faces with fourteen equivalent Fe(1)Ga4Fe8 cuboctahedra. Ga(1) is bonded to twelve equivalent Fe(1) atoms to form GaFe12 cuboctahedra that share corners with twelve equivalent Ga(1)Fe12 cuboctahedra, edges with twenty-four equivalent Fe(1)Ga4Fe8 cuboctahedra, faces with six equivalent Ga(1)Fe12 cuboctahedra, and faces with twelve equivalent Fe(1)Ga4Fe8 cuboctahedra.
