The material structure described by Fe2Ga is alpha La-derived structured and crystallizes in the trigonal P-3m1 space group. Fe(1) is bonded to nine equivalent Fe(1) and three equivalent Ga(1) atoms to form FeGa3Fe9 cuboctahedra that share corners with three equivalent Ga(1)Ga6Fe6 cuboctahedra, corners with nine equivalent Fe(1)Ga3Fe9 cuboctahedra, edges with nine equivalent Ga(1)Ga6Fe6 cuboctahedra, edges with fifteen equivalent Fe(1)Ga3Fe9 cuboctahedra, faces with six equivalent Ga(1)Ga6Fe6 cuboctahedra, and faces with twelve equivalent Fe(1)Ga3Fe9 cuboctahedra.
