研究领域

Inorganic Chemistry

Specializations: X-ray diffraction studies on organometallic and inorganic complexes, with emphasis on derivatives of metal carbonyl clusters and the binding of unusual organic fragments to transition metal centers; crystallographic disorder; hydrogen bonding; absolute configuration. Research Summary: My research group is interested primarily in the determination of the molecular geometry of unusual organometallic molecules. Structural trends and variations in molecular systems are studied and related, where possible, to the formation and reactivity of the individual molecules. For complicated molecules (e.g., substitution products of small metal clusters and high-nuclearity metal clusters), an X-ray diffraction study is often the sole means of determining the stoichiometry and connectivity of the species. Areas of present and future interest include the following: Mononuclear and polynuclear complexes containing unusual organic or nitrogenous ligands – particularly species formed by the scission of multiple bonds and those formed by the fusion of small organic substrates. The geometry of substitution products of metal clusters. Bonding electron density in carboranes and boranes. Methods of solving disordered structures–particularly pseudo-symmetrical metal cluster derivatives. Hydrogen bonding, particularly in solvated crystals. Determination of absolute configuration of chiral molecules.
