The purpose of the study is to study the coordination and chemical properties of bis-chelating carbacylamidophosphates and to obtain and study new luminescent coordination compounds of lanthanides based on them. Research methods - IR, 1H NMR and fluorescence spectroscopy, elemental analysis, thermogravimetry, X-ray diffraction analysis. Twenty-four new compounds were synthesized and isolated in the individual state: two bis-chelated carbacylamidophosphates, their sodium salts and mono- and bio-coordinating compounds, were first obtained and spectrally and structurally characterized lanthanides based on the ligands obtained. Tetramethyl (2,2,3,3,4,4-hexafluoro-1,5-dioxopentane-1,5-diyl) -bis-amidophosphate and tetramethyl (1,3-phenylenedicarbonyl) -bis-amidophosphate are shown to coordinate to metal ions both chelating fragments in a bidentate-chelating manner, forming bioderic complexes, whereas tetramethyl [pyridine-2,6-diildi (iminocarbonyl) diamidophosphate] is coordinated in a monodeprotonated form of tridentate to form mono-nuclear complexes. The position of the lowest triplet level was found tetramethyl [pyridine-2,6-diildi (iminocarbonyl) diamidophosphate] is high enough to provide effective luminescence sensitization of lanthanides.
