This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schiff bases have played an important role in the development of coordination chemistry. The growing importance of the Schiff bases in modern coordination chemistry is attributable to recent observations about their antibacterial and antifungal properties. Lanthanide coordination compounds are the subject of intense research efforts owing to their unique structures and their potential applications. Accordingly, this book contains preparation and characterization of a series of Schiff bases derived from the condensation of benzopyran-4-one derivatives with aliphatic diamines (ethylenediamine and trimethylenediamine), aromatic diamines (o-phenylenediamine and p-phenylene-diamine) and 2-aminopyridine and their antimicrobial activities were screened. The mode of chelation of La(III), Nd(III), Er(III) with these Schiff bases was elucidated by different techniques. The luminescence properties of the prepared Schiff bases and their complexes with Nd(III) and Er(III) ions are also discussed. The book is a valuable study to inorganic chemists those research coordination compounds as well as those looking for a novel approach in drug development.
