We discuss the questions related to modifications of the orthorhombic phase of YBCO. A general approach of statistical mechanics allows to determine numerically such quantities as the paramagnetic Curie constant, concentration of holes doped into Cu(2) planes from chain fragments, the fractions of copper ions in differently coordinated positions. Where the experimental information is available, we discuss a correspondence between our theoretical results end experimental ones.
