We determined the phase diagram of the three-band model for CuO_{2} planes of high temperature superconductors with an attractive interoxygen interaction U_{pp}. The found magnetic moments of 0.47µ_{B} in the undoped system, the disappearance of antiferromagnetic order at the doping of δ ≈ 0.06 hole per CuO_{2} unit, as well as the enhanced tendency to superconductivity with the decreasing value of charge-transfer gap, are in good agreement with the experimental findings.
