Síntese e caracterização estrutural de novos haletos de telúrio e organiltelúrio(IV) com bromo e cloro / Synthesis and Structural Characterization of Tellurium and Organiltellurium (IV) Halides with bromine and chlorine.

Pereira, Cesar Bicca 18 September 2013 (has links)
Conselho Nacional de Desenvolvimento Científico e Tecnológico / This work describes the synthesis and characterization of new tellurium and organiltellurium (IV) halides, whereas the halogens chlorine and bromine were used. Despite being less stable than the analogous iodine, these halides were successfully stabilized by bulky groups and secondary bonds. The structural characterization in the solid state was carried out by X-ray diffractometry, which showed the presence of inter and intramolecular bonds. / Este trabalho descreve a síntese e a caracterização de novos haletos de telúrio e organiltelúrio (IV), sendo os halogênios usados cloro e bromo. Apesar de serem menos estáveis que os análogos de iodo, estes haletos foram estabilizados através de grupamentos volumosos e de ligações secundárias. A caracterização estrutural no estado sólido foi feita por difração de raios-X em monocristal, o que mostrou a presença de ligações inter e intramoleculares.
