Synthesis and Characterization of Transition Metal Complex Systems with Novel Solid State Properties

摘要

The principal focus of this work has been on the preparation and study of pi-donor-acceptor compounds derived from the interaction of planar metal complexes and planar organic molecules. Included among the metal complex system studied are various bis(1,2-ethylenedithiolene) metal complexes, which have been employed as pi-acceptors, and some tetraazamacrocyclic complexes, used as pi-donors. In addition a new planar Ir(I) complex has been prepared using novel redox-active organic ligand system and examined as a source of conductive one-dimensional materials, using iodine to partially oxidize the Ir(I) complex units. These various compounds have been studied using electrical conductivity, magnetic susceptibility, and other solid state property measurement techniques. In addition, their crystal structures have been characterized using single crystal x-ray diffraction methods. The results provide new information regarding the solid state interactions in metal complex-containing systems and suggest the promise of such systems as a soruce of solid state materials with novel magnetic and electronic properties.
