Martell A.E., Smith R.M. Critical stability constants. Volume 2. Amines

Plenum, New York, 1975. — 415 p.Six-volume set tabulating log K values for ligands involved in complexation reactions with protons and metal ions, at various temperatures, primarily 20 or 25 C. Heat and entropy changes are also given where known. Ligands are listed by increasing complexity. Vol.1= amino acids; vol.2= amines; vol.3= organic ligands; vol.4= inorganic complexes; vol.5-6= supplements. This compilation by Martell and Smith has been updated as the "NIST critically selected stability constants of metal complexes database" (NIST Standard Ref. Database 46).Over the past fifteen years the Commission on Equilibrium Data of the Analytical Division of the Inter­ national Union of Pure and Applied Chemistry has been sponsoring a noncritical compilation of metal complex formation constants and related equilibrium constants. This work was extensive in scope and resulted in the publication of two large volumes of Stability Constants by the Chemical Society (London). The first volume, edited by L. G. Sillen (for inorganic ligands) and by A. E. Martell (for organic ligands), was published in 1964 and covered the literature through 1962. The second volume, subtitled Supplement No. 1, edited by L. G. Sillen and E. Hogfeldt (for inorganic ligands) and by A. E. Martell and R. M. Smith (for organic ligands), was published in 1971 and covered the literature up to 1969. These two large compilations attempted to cover all papers in the field related to metal complex equi­ libria (heats, entropies, and free energies). Since it was the policy of the Commission during that period to avoid decisions concerning the quality and reliability of the published work, the compilation would frequently contain from ten to twenty values for a single equilibrium constant. In many cases the values would differ by one or even two orders of magnitude, thus frustrating readers who wanted to use the data without doing the extensive literature study necessary to determine the correct value of the constant in question.
