Abstract

Single-crystal X-ray structure analysis of mutually incommensurate (Sr _0.36Ca_1.64Cu₂O₃) _0.706CuO₂, "Sr_2.5Ca_11.5Cu ₂₄O₄₁" has been performed on the basis of superspace group approach. The lattice constants of (Sr_0.36Ca _1.64Cu₂O₃)_0.706CuO₂ are a = 1.1298(1), b = 1.2582(1), c₁=0.2750(1)nm for the CuO₂ part and a = 1.1298(1), b = 1.2582(1), c₂=0.3897(1)nm for the (Sr_0.36Ca_1.64Cu₂O₃) one. From the average structure analysis, it has been expected that the formation of CuO ₅ with pyramidal coordination by O atoms occurs in the Cu ₂O₃ ladder. The minimum distance between Cu atom in the Cu₂O₃ ladder and O atom in the CuO₂ chain has clearly shown that O in the CuO₂ acts as apical oxygen to form the CuO₅ coordination. It has been concluded that (Sr _0.36Ca_1.64Cu₂O₃) _0.706CuO₂ bears a marked structural resemblance to the cuprate High T_c superconductors.
