This proposal is designed to examine the structures and inter-conversion between polymorphs
of transition metal complexes. The project emphasizes compounds where significant changes
in chemical interactions between molecules produce marked spectral differences between the
polymorphs. Toward the goal of developing these compounds into sensors we will determine
conditions under which the transformations can be made reversible.

have grown and structurally characterized for
dicarbonyl[2(p-tolylimino)penten-3-olato-4]iridium(I)
