Osmium complexes mononuclear, synthesis

Although the above discussion is centered on the synthesis of polymeric osmium and ruthenium complexes, the methods employed are also very successful in the preparation of mononuclear complexes. In this context, the preparation of ruthenium or osmium complexes which are suitable for the formation of self-assembled monolayers (see Section 4.3 above) can be prepared by using the same approach. Starting from the precursor [M(bpy)2Cl2], one chloride atom can be replaced to yield complexes of the type [M(bpy)2Cl L]+, where L is the surface active ligand. In the presence of water, species of the type [M(bpy)2(L)2]2+ are obtained. [Pg.135]

Electrochemical measurements on transition metal complexes are performed for a wide variety of reasons. In this paper we discuss the synthesis of new species by electrogeneration, the measurement of rates of chemical reaction by cyclic voltammetry and the parameterisation of redox potentials within the related series of complexes [OsX. j pyjj], where X = Cl, Br, I, py = pyridine and n = 0-6. A further goal realised by this work was to increase the limited number of Ej/2 values for mononuclear osmium complexes reported in the literature. ... [Pg.69]
