controlled by the O atom modulation in the CuO2. We have further investigated the temperature dependence of the atomic modulations in Sr14Cu24O41, particularly in the CuO2 chain in which the spin-gap behavior accompanied by the formation of the spin-dimerized state is realized at low temperature. By single-crystal x-ray-diffraction method, we have confirmed that superspace group of the modulated structure remains unchanged from room temperature to 150K. The hole distribution has been considered on the basis of the changes of lattice constants, the atomic modulation and the interatomic distances between Cu in the Cu2O3 and O atom in the CuO2. It is indicated that the small amount of holes doped in the Cu2O3 have been backtransferred to the CuO2 and that almost all of the holes are localized in the CuO2 at low temperature. Moreover, the possible hole-ordered structure with the Zhang-Rice singlet in the CuO2 are mainly due to the O atom modulation in the CuO2 and the ZR-singlet site with rectangular CuO4 unit is possible in the CuO2, which is analogous to the local CuO4 coordination in the CuO2 plane of high-Tc cuprates.
