The complexes obtained were Sr[(C9H4ONBr2)2]·2.5H 2O; Sr[(C9H4ONCl2)(OH)]·1.5H2O; Sr[(C9H5ONI)2]·5H2O and Sr[(C9H4ONICl)(OH)]·1.25H2O. The residues of their thermal decomposition were SrBr2; a mixture of SrCl2, SrCO3 and SrO3 SrCO3, and SrCO3, respectively. All were characterized by means of thermogravimetry, differential thermal analysis, complexometry with EDTA, atomic absorption spectroscopy, IR spectroscopy and X-ray diffraction. © 1999 Akadémiai Kiadó.519-524eng8-hydroxyquinoline and its halogenated derivativesDTAStrontiumTGThermal behaviourAbsorption spectroscopyDifferential thermal analysisHalogenationInfrared spectroscopyPrecipitation (chemical)PyrolysisStrontium compoundsX ray diffraction analysisComplexometryHalogenated derivativesHydroxyquinolinesThermogravimetric analysisSynthesis and thermal study of 8-hydroxy-quinoline derivatives of the alkaline Earth metals: I.
