Allowed regions are determined for pair correlations in AyB1 – y solid solutions whose atoms are located at the sites of triangular, square, bcc, and fcc lattices. The problem of determining the probabilities of multiparticle figures is analytically solved with the inclusion of pair correlation ε in the location of nearest atoms for the AyB1 – y solid solutions with triangular, square, bcc, and fcc lattices. It is shown that the presence of the correlation in the first coordination sphere of the AyB1 – y solid solutions with the square and fcc lattices results in the appearance of the short-range order of the opposite sing in the second coordination sphere.
