Structural studies iridium oxygen complexes

Structural studies on the nature of the organometallic intermediates following chelation-assisted CH additions of pincer iridium complexes have been carried out. The product was found to have an unexpected /ram-disposition of the hydride with respect to the metallated aromatic group. This is not the expected direct outcome of a chelation-assisted reaction since coordination of oxygen to iridium prior to C-H activation would be expected to afford the m-isorner (Equation (97)). 

The formation and growth of an electrodeposited phase is a complex process and many methods have been used to study it. The main feature of our laboratory scientific investigations is intensive study of the structure of poly- and monocrystalline refractory metal deposits, such as tungsten, molybdenum, rhenium, iridium, ruthenium and etc. We have shown that the structure of electrodeposited layers directly depends on the conditions of electrolysis [1]. Moreover this structures a most sensitive instrument to study the properties of our electrolyte, including purity of the melt, ion composition, dissipative ability, and kinetic parameters of electrodeposition. It was established that the reduction of oxygen in a chloride melt changed the direction of molybdenum growth texture from <111> to <001 > direction with a fine structure of epitaxial layers [2].
