Summary:Symmetry and structural properties of single state of composite crystal (Ca0.5Y0.5)0.80CuO2, 'Ca2Y2Cu5O10' with one-dimensional CuO2 chain have been investigated by means of the X-ray diffraction method and (3 + 1)-dimensional superspace group approach. By considering the satellite reflections, centrosymmetric superspace groups of (Ca0.5Y0.5)0.80CuO2 have been determined. It has become apparent that 'Ca2+xY2-xCu5O10' phase should be generally described as (Ca0.5+xY0.5-x)*gCuO2, 'Ca5*g(0.5+x)Y5*g(0.5-x)Cu5O10'.
