Transition metal groups 9-11: An introduction

Volume 9 of the Comprehensive Coordination Chemistry III series focuses on groups 9-11 of the transition metal series. Since almost 200,000 new structures containing group 9-11 elements were deposited in the Cambridge Crystallographic Data Centre (CCDC) after 2003, this volume contains chapters focusing predominantly on the types of coordination compounds that have seen the most expansion during the past two decades. For group 9 elements, chapters focusing on coordination compounds with metal-metal bonds, high-valent Rh and Ir compounds, and Rh- and Ir-pincer compounds have been included. In addition, two chapters focus on group 9-11 compounds that contain metal-ligand multiple bonds, and Co/Ni-H2/N2 compounds, respectively. For group 10 elements, four chapters discuss high-valent Ni, high-valent Pd, high-valent Pt, and low-valent Ni/Pd/Pt compounds, respectively. Finally, for group 11 elements one chapter describes Cu compounds involved in transformations involving dioxygen and related oxidation reactions, while the other chapter focuses on high-valent Cu, Ag, and Au coordination compounds.
