Abstract

Modulated structure analysis of the mutually incommensurate composite crystal (Sr₂Cu₂O₃)_0.70CuCO₂ with two-legged spin ladder has been performed on the basis of (3+1)-dimensional superspace group approach. It has been found that the symmetry of (Sr₂Cu₂O₃)0_.70CuO₂ should be described by a centrosymmetric superspace group. In the modulated composite structure of (Sr₂Cu₂O₃)_0.70CuO₂, displacive modulation of O atoms in the CuO₂ chain is fairly large and plays an important role. Structural interaction between the CuO₂ chain and the Cu₂O₃ ladder has been extensively investigated.
