Thermal behaviour and analytical study of the production of TiSnOx from the mixed 8-hydroxyquinolinates

Solubility and pH precipitation studies were carried out to obtain the binu clear complex {[TiO(C9H6NO)(2)][Sn(C9H6NO)(2)]} involving 8-hydroxyquinolin e as chelating agent. The compound, the individual mononuclear complexes an d their physical mixture were evaluated by means of techniques such as TG, DTA, elemental analysis, X-ray diffraction, IR spectroscopy. The properties of the original compounds and also the thermoanalytical conditions exerted a great influence on the degree of crystallinity and on the crystalline ph ase of the mixed oxide obtained as final product of the thermal decompositi on.
