Magnetic Exchange Interactions and Mixed Valence Chemistry in Binuclear Transition Metal Complexes
Binuclear transition metal complexes are of interest because they provide a simple system in which metal-metal interactions can be studied. The importance of understanding these interactions can be seen when one considers the myriad systems which possess such interactions: biological enzymes s

Templating Metal Clusters via Resorcinarene- and Cyclen- Based Ligand Platforms
Polynuclear metal sites, found in both metalloenzymes and heterogeneous catalysts, play a critical role in small molecule activation by enabling multi-electron redox transformations through cooperative reactivity. One of the most compelling examples is biological nitrogen fixation, mediated by the …

The design and synthesis of organic chromophores for Faraday rotation and photoluminescence
… polymers. We demonstrate the presence of strong metal–metal interactions between M(III) centers along the polymer backbone. Further, we discuss the strong phosphorescence and dynamic supramolecular coordination in the solution phase of the Au(I) coordination polymers.

A spectroscopic study of square planar rhodium(I) complexes
… constants are rationalized in terms of the metal-nitrogen bonding, and correlate with the s-character of the bonding electron on nitrogen. While the solution electronic spectra reveal that the complexes are discrete monomeric entities in solution, there are indications of metal-metal …

Novel Organometallic Mixed Valence Complexes
Organometallic mixed valence complexes have been studied extensively over the past 30 years providing many synthetic and theoretical challenges. This thesis has sought to provide the field with a unique family of mixed valence complexes through which theories of electron transfer in weakly coupled …

METAL COMPLEXES AND THEIR BIOLOGICAL ACTIVITY IN VIVO
Luminescent transition metal complexes (TMCs) represent a class of compounds with remarkable photophysical and electrochemical properties, arising from their unique electronic structures. Complexes containing Pt(II), Ir(III), Ru(II), Cu(I) for example are characterized by the presence of partially …

Cyanide-bridged polynuclear complexes
… three mixed valent dinuclear complexes display metal- metal charge transfer (MMCT) bands in the visible region. Some of MMCT properties in the complexes have been analyzed. The cyanide-bridged trans and cis trinuclear complexes with a M’-CN-M-NC-M’ framwork were synthesized and determined by IR, …
