Charge and orbital ordered (COO) phases of an A-site ordered perovskite-type manganite SmBaMn 2O 6 have been investigated using convergent-beam electron diffraction. The space groups of the room-temperature and low-temperature COO phases are revealed to be Pnam and P2 1am, respectively. Based on the space groups, the COO patterns are unambiguously determined. The noncentrosymmetric space group of the low-temperature phase emerging with the re-arrangement of charge and orbitals are revealed.
