THE VOLUME, a collection of forty-nine original scientific contributions, all in English, in memory of Lars Gunnar Sill6n, the late Professor of Inorganic Chemistry at the Royal Institute of Technology in Stockholm, is formally a collection of offprints of the Transactions of the Royal Institute, Nos. 248 296. Scientifically, the papers are subdivided into nine fields: hydrolysis, ionic medium method, anion polymerization, inorganic complexes, organic complexes, ion exchange and extraction, kinetics, structure chemistry and thermodynamics. There are four or five communications in each area, except for the organic complexes and kinetics where there are thirteen and nine papers respectively. Most contributions deal with the formation of metal complexes in solutions, in terms of mass-action law equilibria and stability constants. Regardless of the experimental tools employed, the treatment of the data is that of the Stockholm school. Among the systems reported are the hydroxo and halide, and the mixed hydroxo-halide complexes of nickel, platinum, palladium, lead, iron, uranium, beryllium, iridium and yttrium; polyanionic complexes of molybdic, tungstic and phosphoric acids, and oxyhalomolybdates and tungstates; transition metal complexes with sulfur containing organic donor molecules; carboxylic and other organic acid complexes of cadmium, iron, calcium, uranium and some lanthanides; copper and zinc complexes of amino acids and of a number of related compounds of biological importance; EDTA complexes of molybdenum; diketones of gallium and tributylphosphates of uranium. There are several papers dealing with acid-base equilibria, acid-salt and buffer systems, association of carboxylic acids and alkylammonium salts in nonaqueous media, and thermo-

dynamics of strong electrolytes and high temperature processes. Five papers are concerned with X-ray data on solid inorganic complexes, including the symmetry and stereochemistry of complex ions, the structure ofhydroxocomplexes of lead, bismuth oxide and mercury sulfide. One paper describes the applicability of low angle X-ray scattering for the identification of complex species in solutions. Finally, some of the contributions are of a review nature rather than original papers. Reviewed are the hydrolysis and polynucleation equilibria in terms of the core-plus-link concept, tungstate chemistry, symmetry of complex ions, and briefly, the importance of constant ionic media for studying complex formation in solution and, equally briefly, polynuclear complexes with bridging ligands. The volume is a fine collection of excellently written scientific contributions of authors well known in the general field of the title topic. It is of course not surprising that almost half of the authors are Scandinavians, but is perhaps noteworthy that only three papers came from the U.S., while ten have been written by authors from Russia and Eastern Europe. The book is well and uniformly edited and of a high quality production, printed on glossy paper and free of printing errors. The book is a welcome contribution to the field, and apart from the valuable scientific information it contains, may be also useful to newcomers who wish to adopt the thermodynamic approach of treating complex formation reactions in solution. While not a textbook, the methods of investigations described and exemplified on a variety of systems, along with the modes of computation of equilibrium constants, may also serve as a teaching tool for graduate courses on the topic.
