В работе исследована агрегативная способность комплексов Pt(II) на основании данных эксперимента титрованием 1H ЯМР и DOSY. Приведен вывод уравнений статистико-термодинамической модели, описывающей процесс агрегации. Рассчитаны количественные параметры самоассоциации металлокомплексов.

Using experimental titration 1H NMR and DOSY data the ability of Pt (II) complexes to aggregate was investigated. The equations of statistical-thermodynamic model describing aggregation process were derived. Quantitative parameters of self-association of metal complexes were evaluated.
