摘要

A new phosphoryl-containing ligand based on 4-aminoantipyrine-N- (1,5-dimethyl-3-oxo-2-phenyl-1,2-dihydropyrazol-4-yl) -P,P-diphenylamidophosphinate (L) was synthesized. In crystals, the L molecules were found to be combined in centrosymmetric dimers through N–H···O=C hydrogen bonds. The complexes of L with neodymium(III), erbium(III), thorium(IV), and uranyl nitrates were obtained, and their structures were determined. The bands of the C=O and P=O groups in the IR spectra of these complexes are shifted toward low frequencies (by 50–65 and 40–70 cm~(–1), respectively), which is indicative of a bidentate coordination of the organophosphorus ligand. According to the X-ray crystallography data, uranyl is biden-tately coordinated by both the L molecule (through the C=O and P=O groups) and two nitrate anions.
