Abstract

Frozen aqueous solution of hyperalkaline tin(II)-hydroxide was analysed by Sn-119 Mossbauer spectroscopy at low temperature in order to determinate the structure of the hydroxo complex formed under hyperalkaline (pH > 13) conditions. Interestingly, the quadrupole doublet characteristic of this complex in the Sn-119 Mossbauer spectrum exhibited asymmetry in the line intensities. Analysis of the temperature dependence of the Mossbauer spectra demonstrated that this phenomenon can be rationalised by the Goldanskii-Karyagin effect. The effect emerges due to the vibrational anisotropy of bonds in the tin complex formed in hyperalkaline solution, similarly to what has been found earlier for SnF2 with analogous Sn bond structure.
