B vitamin, contains cobalt and
in methanogenic bacteria converts carbon dioxide to methane. The naturally occurring molecules are often very complex and difficult to study because there are usually associated with proteins. One approach used to help chemists understand complex processes is to make model compounds which have characteristics similar to the natural molecule. Model compounds can often provide insight into the important factors of the structure of the naturally occurring complexes as well as giving information into the design of systems which can mimic biological behavior. Much of the research in this area has involved such topics as catalysis, organic synthesis, and analytical methods in both industrial and medicinal applications.
II. Another research project in my group involves the investigation of the geometry and coordination preferences of metal ion complexes with multidentate ligands. When a ligand has several possible coordination sites, the ones used in coordination depend on a combination of the preferred geometry of the metal ion, the hard/soft nature of the ligand and the metal ion, and the geometry of the ligand. We have been investigating a class of ligands based on di-2-pyridyl ketone (DPK). In particular, new ligands containing O, S, and N in 5- and 6- membered rings are being synthesized. The coordination of these ligands with a variety of transition metal ions can be studied through the use of X-ray crystallographic techniques.
