Fluoride coordination compounds of metals with amino acids – a new class of fluoride metal complexes. R.L. DAVIDOVICH (Institute of Chemistry, FEB RAS, Vladivostok).
It has been formed a new class of fluoride complexes of metals – coordination fluoride compounds of metals with amino acids. It has been defined two types of coordination fluoride compounds of metals with amino acids – neutral molecular and anionic coordination compounds. In molecular coordination fluoride compounds of metals, the amino acids have deprotonated zwitterionic form and are ligands. The amino acids are coordinated to the metal atom with the carboxyl oxygen atoms of amino acid forming the coordination metal polyhedron along with fluorine atoms. Anionic coordination fluoride compounds of metals contain amino acids in protonated state, as cations in coordination compounds. 34 fluoride coordination compounds of III–V group metals with various amino acids are synthesized and investigated by IR spectroscopy and X-ray diffraction methods. Crystal structures are determined for 22 of them. The structure of the obtained coordination fluoride compounds of metals with amino acids is being discussed.
