Dr. Sergiy Kryatov did research on the analytical
applications of coordination compounds under the guidance of Prof.
Lev Budarin and Dr. Vitaliy Pavlishchuk as a part of the Ph. D.
program at the Pisarzhevsky Institute of Physical Chemistry (Kiev,
Ukraine) in 1991-1997. Reactions of a series of metal
aminopolycarboxylates ML (M = Co, Ni, Cu, Zn; L = Nta, Edta) with
volatile amines A (NH3, N2H4) were
studied in solution and in solid/gas systems. Composition and
structure of the resulting heteroligand complexes MLA were
determined by spectroscopic and other means in aqueous solution,
solid amorphous state, and solid crystalline state. Quantitative
studies on the reactions of solid ML with gaseous A to yield solid
MLA were performed using the piezo-acoustic microbalance technique.
This method allowed for the analytical determination of the amine
vapor in air.
Dr. Kryatov has done experimental research in
inorganic chemistry, bioinorganic modeling chemistry, and
coordination chemistry in the laboratory of Prof. Elena
Rybak-Akimova at Tufts University. Some of these research projects (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) are featured on the web-site of Prof.
Rybak-Akimova (http://ase.tufts.edu/chemistry/rybak/research.htm).
