An ordered arrangement of carbon and copper atoms in the new compound (C0.4Cu0.6)Sr2(Y0.86Sr0.14)Cu2O7 was investigated by means of electron diffraction and high-resolution electron microscopy. Electron diffraction patters show diffuse superlattice reflections corresponding to a compositional modulation with periods in the range from 2a to 3a along the a-axis and 2c along the c-axis. From observed high-resolution images, it is concluded that the modulated arrangement of carbon and copper atoms is responsible for the diffuse superlattice reflections. It is proposed that this modulated structure consists of two kinds of superstructure units having dimensions of 2a×b×2c and 3a×b×2c. There are two different atomic arrangements in the 3a×b×2c units.
