Inverse Coordination Chemistry

Ionel Haiduc is Professor Emeritus at Babes-Bolyai University in Cluj-Napoca, Romania. A distinguished chemist and prolific researcher, he has published over 340 journal articles and authored several books including The Chemistry of Inorganic Ring Systems (1970), Basic Organometallic Chemistry (1985), The Chemistry of Inorganic Homo- and Heterocycles (1987), Organometallics in Cancer Chemotherapy (1990), and Supramolecular Organometallic Chemistry (1999). He is a member of the Romanian Academy (former President from 2006 to 2014) and the Academia Europea (London), as well as an honorary or correspondent member of Göttingen Academy of Sciences and Humanities, Hungarian Academy of Sciences, Academy of Sciences of Moldova, and Montenegrin Academy of Sciences.Edward R.T. Tiekink is Distinguished Professor and Head of the Research Centre for Crystalline Materials at Sunway University, Malaysia. He is a graduate of the University of Melbourne, Australia (D.Sc. 2006), where his passion for structural chemistry was nurtured. He has published in excess of 2,000 research papers/reviews and co-edited a number of books reflecting his interests in crystallography and metal-based drugs, including Metallotherapeutic Drugs and Metal-Based Diagnostic Agents: The Use of Metals in Medicine (2005), Frontiers in Crystal Engineering (2006), Organic Crystal Engineering—Frontiers in Crystal Engineering (2010), and Multi-Component Crystals: Synthesis, Concepts, Function (2017). He is a Fellow of the Royal Society of Chemistry and the Royal Australian Chemical Institute.
