Tozhiboev, B. Tashkhodzhaev, K. Turgunov, N. Mukarramov, Kh. Shakhidoyatov] The structures of mixed crystals — solid solutions in the peganole-brompeganole system with molar ratios 0.72:0.28, 0.32:0.68, 0.10:0.90 and of pure peganole are determined by single crystal X-ray diffraction. It is shown that the solid solutions (mixed crystals) exist as three different phases. These crystal structures tend to form closed centrosymmetric dimers involving two molecules (probably different) joined by "anti-parallel” centrosymmetric hydrogen O-H...N(1) bonds. The development of this dimer is the cause of forming mixed crystals in the peganole-brompeganole system.
