Book Description
This book contains an overview of complex formation by macrocyclic ligand systems. The study of macrocyclic chemistry represents a major area of activity which impinges on a range of other areas in both chemistry and biochemistry. The field has characteristically yielded many interesting and unusual compounds. The text discusses the structures and properties of macrocyclic compounds; the synthesis of macrocycles; polyether crown and related systems; metal-ion and molecular recognition (host-guest chemistry); as well as kinetic, thermodynamic and electrochemical aspects of a range of macrocyclic systems. A discussion of the different categories of naturally occurring macrocycles is also included. Specialist and non-specialist alike will find this a useful text. Apart from serving as a convenient reference for established workers in the field, it should also prove useful to new graduate students as well as to researchers from other areas who seek a general introduction to the subject.

Book Description
Chemists have been aware of the existence of coordination compounds con taining organic macrocyclic ligands since the first part of this century ; however, only during the past few years have they expanded research into the chemistry of these compounds. The expansion was initiated in the early 1960s by the synthesis and characterization of compounds containing some new macrocyclic ligands. The synthesis of compounds which may serve as model systems for some natural products containing large rings as ligands provided the main goal for the early expansion of research effort; indeed, a recurrent theme behind much of the reported chemistry has been the analogy between synthetic macrocyclic compounds and many natural-product systems. More recently, the emphases of reported research have ranged over the whole spectrum of chemistry, and the number of publications that discuss macrocyclic chemistry has increased at a dramatic rate. The completed research has been reported in a variety of journals throughout the world but there has been no previous attempt to bring the major developments together under one cover. This book, therefore, attempts to satisfy the need for a single source in which there is both a collection and a correlation of information concerning the coordination chemistry of macrocyclic compounds. The chapters in this book discuss various aspects of macrocyclic chemistry, and while these chapters as a whole constitute an in-depth survey of the state-of the-art of the field, each chapter is written as a complete unit.

Book Description
Stability constants are fundamental to understanding the behavior of metal ions in aqueous solution. Such understanding is important in a wide variety of areas, such as metal ions in biology, biomedical applications, metal ions in the environment, extraction metallurgy, food chemistry, and metal ions in many industrial processes. In spite of this importance, it appears that many inorganic chemists have lost an appreciation for the importance of stability constants, and the thermodynamic aspects of complex formation, with attention focused over the last thirty years on newer areas, such as organometallic chemistry. This book is an attempt to show the richness of chemistry that can be revealed by stability constants, when measured as part of an overall strategy aimed at understanding the complexing properties of a particular ligand or metal ion. Thus, for example, there are numerous crystal structures of the Li+ ion with crown ethers. What do these indicate to us about the chemistry of Li+ with crown ethers? In fact, most of these crystal structures are in a sense misleading, in that the Li+ ion forms no complexes, or at best very weak complexes, with familiar crown ethers such as l2-crown-4, in any known solvent. Thus, without the stability constants, our understanding of the chemistry of a metal ion with any particular ligand must be regarded as incomplete. In this book we attempt to show how stability constants can reveal factors in ligand design which could not readily be deduced from any other physical technique.

Book Description
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. This book will give an in-depth account of the properties of Schiff base and their metal complexes. This book will discuss the details of synthesis methods for Schiff base and their metal complexes. This book will cover emerging trends in the use of Schiff base metal complexes in the industry. This book will provide an overview of the wider biological applications of Schiff base metal complexes
