Inorganic Chemistry. Dr. Kryatov's research interests have been in the analytical applications of coordination compounds. His research has been involved with reactions of a series of metal aminopolycarboxylates ML (M = Co, Ni, Cu, Zn; L = NTA, EDTA) with volatile amines A (NH3, N2H4) in solution and in solid/gas systems. These reactions have been used to determine the composition and structure of the resulting heteroligand complexes MLA by spectroscopic and other means in aqueous solution, solid amorphous state, and solid crystalline state. He has also performed quantitative studies on the reactions of solid ML with gaseous A to yield solid MLA using the piezo-acoustic microbalance technique, which allowed for the analytical determination of the amine vapor in air. In collaboration with Prof. Rybak-Akimova at Tufts, Dr. Kryatov has also done experimental research in inorganic chemistry, bioinorganic modeling chemistry, coordination chemistry, specifically, the use of dinuclear metallocomplexes as bioinorganic models, mechanisms of oxygen and peroxide activation at metal centers, kinetic and mechanistic studies of biomimetic complexes, and activation of nitrous oxide by molybdenum complexes.
