During the past few decades, considerable attention has been paid to the chemistry of the coordination compounds. Co-ordination compounds in which the central metal ion is bounded to different Ligands exhibit different characteristic properties. The characteristics of such compounds are based on nature of metal as well as the type of ligands and their structures. In the present book, series of Copper(II), Nickel(II) and Cobalt(II) complexes derived from 4,6-diacetylresorcinol have been prepared. The ligands and their metal complexes have been characterized by FT-IR, Mass, 1H NMR, UV-Vis.,...

The key objective of this work is to measure total concentration of metals like Zn, Cu, Fe, and Mn in the industrial dust particles settled outside the processing site of brass foundries by using different analytical techniques; such as DTPA extraction, acid digestion methods and analysis of metals using Atomic Absorption Spectrophotometer.Industrial dust particles from brass foundries contains large amount of Zinc and Copper. This contains too the considerable amount of Iron and Manganese. Analyzing these dust particles help us to understand the need of managing them in proper way, which...

The use of Schiff bases as ligands has enjoyed a very rich history with importance of metal complexes in a variety of industrial and biological applications. Stereochemical flexibility is well documented among Schiff-base complexes arising from central metal, the source of the carbonyl function, the amine, as well as substituents on and steric bulkiness around the Schiff base. Schiff bases accommodate different metals with various coordination modes allowing synthesis of stable complexes with varied stereochemistry. Numerous Schiff bases and their transition metal complexes have been...
