To study the stability of complexes by various parameters specially with softness parameters
Author(s): Dr. Dilip Shukla
Abstract: Pearson (1) in 1963 was introduced H.S.A.B. Principle. He suggested that hard acids prefer to bind with hard bases and soft acids to soft bases. Though Pearson was the first author of H.S.A.B. principle yet a number of earlier papers have been a source of ideas and inspiration. The first paper in this regard was published by Edward (2) in which he introduced a four parameters equation to describe the stability of the compounds. In 1956 Schwarzenbach (4) and Ahrland Chatt and Davis (5) classified the metal ions into two classes ‘a’ and ‘b’ type. They explained that class ‘a’ type of metals prefer to bind with class ‘a’ type of donors and similarly class ‘b’ type of metals prefer to interact with class ‘b’ type of donors. Since it was described that class ‘a’ type of metals prefer to interact with class ‘a’ type of ligands. It was conceived that such an interaction shall lead to the formation of a more stable compound. Schwarzenbachin 1961 presented a detailed account on the factors influencing the stabilities of metal complexes (6). In his description he pointed outthat class ‘b’ type of metals form more stable complexes with class ‘b’ type of ligands.
