“Coordination Compounds of Transition Metal Ions with Mono-, Tri- and Pentacyclic Aromatic Systems of Azole Derivatives”

Abstract:

Mono- bis- and tris-azole heterocyclics play important biological roles; these polyfunctional molecules bear nitrogen, oxygen and sulfur atoms as basic sites for coordination. These bidentate ligands may give place to a variety of metal-ligand coordination modes. They may favor the formation of six-membered rings, by inclusion of a metal ion in a planar delocalized system, and promote intra- and inter-molecular interactions, such as hydrogen bonding and π-stacking, yielding supramolecular aggregates. Our main goal is to study the effect of heteroatoms (nitrogen, oxygen or sulfur) in these aromatic N-donor molecules upon coordination towards Co(II), Ni(II), Cu(II), and Zn(II) ions, and their effect on their chemical and structural behavior.

Dr. Barba-Behrens is a Professor in the Department of Inorganic and Nuclear Chemistry at the National Autonomous University of Mexico (UNAM). She received her Ph.D. degree in inorganic chemistry from the Imperial College of Science and Technology in London (1979) and a B.S. in chemistry from the UNAM in 1970. Her research interests are in synthetic bioinorganic chemistry, including the coordination chemistry of biologically relevant molecules such as imidazoles and benzimidazoles, and the preparation of transition metal complexes exhibiting antibacterial or antineoplastic activity, as documented in more than 70 peer-reviewed publications.
