The manganites with general formulae R0.5A0.5MnO3 (3D-manganite), R0.5A1.5MnO4 (layered manganite), and RA2Mn2O7 (bilayer manganite), where R3+ is rare-earth ion, A2+ is alkaline-earth ion, are known as charge ordered compounds at low temperatures with some R and A. In present work, it is shown how the charge ordering and crystal structure form the orbital and magnetic ones. The model of orbitally-dependent superexchange and single-ion anisotropy is used. Also we assume an ideal insulating state of the crystals. The model presented in this work allows to explain the CE- and A- magnetic structures in the terms of charge and orbital structures.
