The content of the third edition has gone through significant changes with the entire book modified and updated to take into account the developments in the field since the last edition published, as well as based on the readers experience with the use of the book. The most significant changes are due to Chapters 5, 7, and 11. Chapter 5 has been thoroughly rewritten to take into account the fast developing methods of ab initio calculations of electronic structure of coordination compounds.

Similarly, chapter 7 includes the latest developments in application of vibronic coupling and the Jahn-Teller and pseudo Jahn-Teller effects to solve coordination chemistry problems. In chapter 11, the more up-to-date views on reactivity, chemical activation, and catalysis are discussed, including the role of the pseudo Jahn-Teller effect.

Additionally the questions, exercises, and problems to each chapter of the book have been reviewed and extended, and more problem solving examples are included. Similarly, additional illustrations, graphic presentations, and references have been added.
