Takashiro Akitsu, PhD, has been a full Professor for the Department of Chemistry, Faculty of Science Division II, at Tokyo University of Science since 2016.

He completed his undergraduate school training (chemistry) and his graduate school training (physical and inorganic chemistry, especially coordination and crystal and bioinorganic chemistry) at Osaka University in 1995 and 2000, respectively. Dr. Akitsu

has published many articles in journals while working at Osaka University (2000– 2002), Keio University (2002–2008), and Tokyo University of Science (2008–present). He has been a peer reviewer of many journals and acted on the organizing committees of several international conferences. His research interests are crystal and electronic structures of chiral metal complexes and their hybrid materials.

Preface

This book reviews a wide range of both current research in and several principles of crystallography, not only for natural sciences, mathematics, physics, chemistry, biology, and earth sciences but also for applied engineering such as material and medical or pharmaceutical sciences. As a review book on crystallography, this book will help with theoretical considerations and understanding the basic theory of

2. Techniques of crystal structure analysis such as experiments on neutron diffraction, computational methods about phase problem, and commonly used

3. Compounds or topics solved by crystallography such as a review of structural inorganic chemistry and hydrogen bonds in the crystal chemistry of organic
