Coordination States and Catalytic Performance of Ti in Titanium Silicalite-1 *by Yi Zuo, Min Liu and Xinwen Guo*

Preface

Among various research studies done in chemical sciences by researchers around the globe, coordination chemistry has had a prominent position due to the versatile use of coordination compounds. Interest of researchers in this field is also due to ease of synthesis process of mono-metallic to multi-metallic compounds with flexible, simple lone pair/s donating organic, and inorganic moieties. Engagement of chemists and material scientists in designing potent lone pair rich ligands and their complexes as well in recent years is a ray of hope to enrich our scientific community with high grade metal-based molecules for their utilization in

different fields of social wellness. The present compilation is the research findings, thoughts, and scientific views of researchers on coordination compounds with special attention on their stability and wide applications. The efforts of authors are presented here as an edited book and divided in nine chapters, accordingly. The chemical aspects of discussions have been accentuated to a great extent as well as relevant physical and spectroscopic data have also been incorporated. Moreover, simple analogies and graphics have been used to explain concepts in easier way. It is a structured attempt to present the matter in a comprehensive manner so that the personnel from research, academic, and industrial backgrounds are able to enhance their knowledge and expertise about the current situation and future possibilities in this emerging field of chemical research. However, post-graduate level chemistry students may also benefit from this book as the study of coordination compounds has been introduced in the syllabus of nearly all universities in the world. As an editor, I believe that every person dealing with coordination chemistry will be advantaged with this book. Furthermore, I am very obliged to the authorities of Nitishwar Mahavidyalaya (B.R.A. Bihar University), Muzaffarpur, India for providing creative and encouraging environments throughout the progress of this book project. Faculty members of the Post Graduate Department of Chemistry, B.R.A. Bihar University, Muzaffarpur, India also deserve a thank you for fruitful discussion about this project. For the most, I am grateful to Dr. Netrapal Singh, Associate Professor, Department of Chemistry, D.D.U. Gorakhpur University, Gorakhpur, India whose assistance throughout made this job easier. I am also thankful to my family members for their support and patience. Finally, I owe my hearty thanks to all the authors who contributed chapters for the book and also to the entire team of IntechOpen, London, United Kingdom for taking responsibility
