Irving Department of Inorganic Chemistry, University of Cape Town, Rondebosch, Cape Town, South Africa Abstract - Coordination compounds are used in almost every branch of analytical chemistry. Variety of metallurgical processes, industrial catalysts and analytical reagents involve the use of coordination compounds. Abstract. Metal complexes have a lot of useful applications in organic and organometallic chemistry, catalysis [1], medicine as anticancer pharmaceutics and for drug delivery [2], various biological systems [3], polymers [4] and dyes, separation of isotopes [5], and heavy metals [6], among many other uses. In the human biological system, several coordination compounds play important roles. The mode of action of medically relevant coordination and organometallic compounds in a biological environment is crucially dependent on their interactions with biological molecules. Coordination compounds also have major importance in biological systems. (iii) A complex of zinc(II) called enzyme CPA helps in digestion of food. • In modern terminology, these compounds are called coordination compounds. Featuring contributions from a team of international experts in the coordination chemistry of biological systems, this book enables readers to understand and take advantage of the fascinating internal molecular environment of protein cages. Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkaline, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and tin, as well. The disulfide bond plays an important role in the formation and stabilisation of higher order structures of peptides and proteins, while in recent years interest in this functional group has been extended to carbohydrate chemistry. The course utilizes examples from bioinorganic chemistry to introduce advanced topics in synthesis, structural analysis, and analytical methods that are practiced by inorganic chemists. An intriguing aspect of vitamin B12 is the great stability of the metal-carbon bond.

COORDINATION COMPOUNDS IN ANALYTICAL CHEMISTRY Harry M.N.H. Metal ions are very widespread in biological systems: some are present in enzymes, some in structural features like the calcium in bones, some in transport systems like the iron in haemoglobin, some in control systems like … Coordination compound • Complex compounds are a special class of compounds in which the metal atoms (or) ions are bound to a number of anions (or) neutral molecules. The two major components of bioinorganic chemistry are: i) the study of naturally occurring inorganic elements in bio-systems and ii) introduction of these elements as probes or drugs into biological systems and studying inorganic models that mimic the behavior of various metallo-proteins. Coordination compounds play a vital role in analytical chemistry, metallurgy, biological systems, industry and medicine. Coordination complexes are very useful in the extraction of many metals from their ores. COMPREHENSIVE COORDINATION CHEMISTRY II. 3. This pigment is a coordination compound of magnesium. It is essential to identify new compounds that selectively inhibit tumor proliferation, evading secondary effects and resistance associated with chemotherapeutics. Extraction processes of gold and silver are done by making use of the coordination compounds. application. Some of the important applications of coordination compounds are as follows: Coordination compounds like Na 2 EDTA are used for the detection of the hardness of the water. Inorganic chemistry faculty at Virginia Commonwealth University (VCU) are offering an advanced, interdisciplinary, graduate course entitled "Applications of Inorganic Chemistry in Biology". The history of forensic chemistry is holding the facts of methods developed by a scientist for the identification and analysis of poisons, which were used for the commission of murders. A Brief History of Forensic Chemistry. Coordination compounds offer many binding modes to polynucleotides, includ-ing outer-sphere noncovalent binding, metal coordination to nucleobase and phosphate backbone 810 Metal Complexes as Drugs and Chemotherapeutic Agents 6. vital components of biological systems. Coordination Compound. Since the discovery of cisplatin, a wide variety of metal complexes have been designed for the treatment of cancer and other diseases as well as for diagnostic purposes. Coordination compound By azim 2. Biological system:(i) Haemoglobin the red blood cell which acts as oxygen carrier to different parts of the body is a complex of iron(II).
