Abstract

Frozen aqueous solution of hyperalkaline tin(II)-hydroxide was analysed by 119Sn Mössbauer 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 119Sn Mössbauer spectrum exhibited asymmetry in the line intensities. Analysis of the temperature dependence of the Mössbauer 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.
