Chemistry of Complex Equilibria (dedikált példány) [antikvár]

PREFACE During the last two decades an enormous amount of information concerning complex equilibria has been published. Many experimental methods have been devised to obtain quantitative data on complex formation, and calculation methods have been developed for the evaluation of stability constants from such data. In addition, thousands of important papers, and some excellent reviews and books have appeared. The most comprehensive of these books is The Determination of Stability Constants by F. J. G. Rossotti and H. Rossotti, a fundamental mathematical treatment of most aspects of complex equilibria in solution, with which I in no way intend to compete here. I feel, however, that perhaps none of these publications gives a sufficiently broad and realistic account of complex equilibria, the chemistry often remaining hidden behind the algebraic equations. One fact in particular has not been adequately pointed out, viz. that the formation of mononuclear complexes with one kind of ligand only, a problem considered in most of the papers, occurs only under fairly artificial conditions. In fact, the only complex equilibrium which does not involve species other than mononuclear complexes with a completely homogeneous co-ordination sphere is the formation of a co-ordinatively saturated complex in a single step. In the present treatment, therefore, a much stronger emphasis is laid on mixed ligand, protonated, polynuclear and outer-sphere type complexes, which are treated in some detail. These species are still frequently regarded as somewhat exotic, but their existence must be taken into consideration in general. This book is based on a Hungarian version originally published in 1965, but has been completely rewritten and the literature intended to be covered up to 1968. I should like to express my gratitude to Professor P. Huhn for many discussions, to Professor J. B^errum for his critical comments on a considerable part of the manuscript, to Professor J. Rydberg for an unpublished
