Summary of Research Interests
Our group is involved in the synthesis and magnetic
characterization of mono- and dinuclear transition metal
complexes. For complexes of iron, these investigations provide
information on the conditions necessary for the stabilization
of admixed and intermediate spin states and spin crossover
behavior, phenomena relevant to the understanding of some
metalloenzyme functions. Also of interest is the investigation
of magnetic coupling between paramagnetic metal centers and,
in particular, the effect of crossover behavior in one metal
on the type of coupling observed in the dinuclear system. As
part of studies related to cytochrome-based biological systems
we are investigating the reduction of iron(III) porphyrin
systems by amines, the synthesis of stable iron(III) porphyrin
thiolate complexes and the synthesis of thiolate bridged
dinuclear complexes of metalloporphyrins.
