For example, a mixture of [TmBut]ZnMe and Me2Cd form an equilibrium mixture with [TmBut]CdMe and Me2Zn. Furthermore, transfer of the [TmBut] ligand between the metal centers is possible too. This is demonstrated by the transfer of [TmBut] from mercury to zinc in the methyl system, [TmBut]HgMe/Me2Zn. Additionally, transfer of [TmBut] from zinc to mercury is also observed upon treatment of [TmBut]2Zn with HgI2 to afford [TmBut]HgI and [TmBut]ZnI, thereby indicating that the nature of the co-ligand has a profound effect on the thermodynamics of ligand exchange. Chapter 3 explores the coordination chemistry of the selenium donor ligand, H(sebenzimMe). H(sebenzimMe) is able to coordinate metal centers through the selenium atom in a dative fashion, and, depending upon the metal center, up to four H(sebenzimMe) ligands can coordinate the same metal. Additionally, H(sebenzimMe) can be deprotonated to form [sebenzimMe]–, allowing for the potential of an LX coordination mode, which results in bridging complexes for the metal compounds investigated.

Hydrotreating catalysis with transition metal sulphides is one of the most important areas of industrial heterogeneous catalysis. The present book deals with the chemical and catalytic aspects of transition metal sulphides, focusing on their use in hydrotreating catalysis. The book¿s 12 chapters present reviews of solid-state, coordination and organometallic chemistry, surface science and spectroscopic studies, quantum chemical calculations, catalytic studies with model and real catalysts, as well as refinery processes. A presentation of state-of-the-art background to pertinent work in the field. Can be used as an introduction to the chemical and catalytic properties of transition metal sulphides as well as an advanced level reference.
