Abstract

Complex compounds of neodymium(III) with a quinaldic acid anion and nitrogen- and phosphorus-containing neutral ligands have been synthesized. The mixed-ligand compounds were characterized by elemental and X-ray diffraction analysis and IR spectroscopy. The thermal behavior of the obtained compounds was studied by thermal analysis in air in the temperature range 25–700°C. During the thermolysis of the complexes, the neutral ligand molecule is eliminated in one stage with an endothermic effect; the compounds are thermally stable up to 250°C. It was established by IR spectroscopy that in mixed-ligand neodymium(III) quinaldinates, the acid anion is coordinated to the central neodymium(III) ion as a bridging bidentate ligand. The luminescence properties of neodymium(III) quinaldinates were studied.
