Description

The gel formed by alkaline precipitation of aqueous tin(IV)chloride and allowed to dry at room temperature gives a single somewhat broad line Moessbauer spectrum. The transformation of this material to stannic oxide proceeds through intermediate dehydration species which give quadrupole split Moessbauer spectra reflecting the initial increase and subsequent decrease in asymmetry at the tin oxyhydroxide nucleus. The electric field gradient at the tin nucleus in stannic oxide is attributed to its crystal structure rather than deviation from stoichiometry. (orig.)

Abstract (German)

Das durch alkalische Faellung aus Zinn(IV)-chlorid erhaltene und bei Zimmertemperatur getrocknete Gel ergibt ein einfaches, etwas breitliniges Moessbauerspektrum. Die Ueberfuehrung dieses Materials in Zinn(IV)Oxid fuehrt ueber einige Dehydrationszwischenstufen, die eine Quadrupolaufspaltung im Spektrum liefern, die auf die anfaenglich ansteigende, dann abnehmende Asymmetrie beim Zinnoxyhydroxidkern hinweist. Der elektrische Feldgradient beim Zinnkern im SuO2 ist mehr durch die Kristallstruktur bedingt als durch eine stoechiometrische Abweichung. (orig.)
