Direct Synthesis of Metal Complexes provides in-depth coverage of the direct synthesis of coordination and organometallic compounds. The work is primarily organized by methods, but also covers highly relevant complexes, such as metal-polymer coordination compounds. This updated reference discusses recent developments in cryosynthesis, electrosynthesis, and tribosynthesis (popular as it doesn't require organic solvents), with special attention paid to 'greener' methodologies and approaches. Additionally, the book describes physical methods of zero-valent metal interaction with organic matter, including sputtering, ultrasonic treatment and synthesis in ionic liquids. The book presents completely new content as a follow-up to the 1999 Elsevier Science publication Direct Synthesis of Coordination and Organometallic Compounds that was edited by Dr. Garnovskii and Dr. Kharisov. - Covers current methods and techniques of metal interactions with organic media leading to metal chelates, adducts, di- and polymetallic complexes, metal-containing macrocycles, supported coordination compounds (i.e., metal complexes on carbon nanotubes), and more - Describes reactivities of distinct forms of elemental metals (powders, sheets, nanoparticles (including a host of less-common metal nanostructures) with organic phase (liquid, solid and gaseous) and water - Includes experimental procedures, with examples of direct synthesis, at the end of each chapter

Coordination compounds have been well-known for their wide variety of applications for over a century, as well as enhancing the researcher’s interest and concern in evaluating their action mechanism. It is certainly one of the most intensely discussed research topics. Coordination compounds involve different metal-ion-ligand phenomenon. The involved metal ions play a significant role in structural association and functioning of several processes in the genetic and metabolism system. In recent years, Schiff base ligands have gained significant interest and received a keen interest of many researchers. Schiff’s base ligands have been recognized to hold a wide variety of biological and medicinal activities due to the presence of donor atoms. They have proved exceptional pharmalogical actions such as antimicrobial, anti-tuberclosis, antiplatelet, antidiabetic, antiarthritis, antioxidant, anti-inflammatory, anticancer, antiviral, antimalarial, and analgesic. These biologically active Schiff base ligands have also been shown to inhibit enzyme mobilization and, when bound to a metal ion, exhibit enhanced biological activity, making them useful in a number of fields. As a result, metal complexes of Schiff base ligands are gaining popularity due to their unique properties and functionalities. Schiff base complex-based research for educational and industrial purposes is booming, and the number of publications is gradually increasing. Despite these interests, there is currently no detailed book on Schiff base metal complexes that covers the structures, biological activities, and other non-biological perspectives. This book delves into the structures of Schiff base metal complexes, which are critical in assessing the biological viability of any complex. It also highlights their biological significance in pharma and drug discovery like antibacterial, antifungal, anticancer, anti-inflammatory, anti-arthritis, anti-diabetic, antioxidants, anti-proliferative, antitumor, anticancer, antiviral. The fundamentals of metal complexes are described, as well as an up-to-date outline of developments in synthesis, characterization methods, properties- chemical, thermal, optical, structural, and applications. This book also discusses the other applications of Schiff base metal complexes: as sensor (luminescent, electrochemical, and biosensor), as pigments in dying and paint industries, as photocatalyst to improve the degradation rate. Features : This book would be useful for academia, researchers and engineers working in the area of Schiff base and their metal complexes.
