摘要：

The Sn-119 Mossbauer parameters delta, isomer shift, and DELTA-E, nuclear quadrupole splitting, have been determined in frozen aqueous solutions of Me2Sn(IV) and Me3Sn(IV) moieties at varying pH. The resulting functions nBAR versus pH (where nBAR is the average number of protons released per mole of the organotin aquocation) agree satisfactorily with functions from potentiometry. The structures of the aquocations, as well as of the hydroxides, and of the mono-hydroxo complex [Me2Sn(OH)(OH2)n]+, are correlated to the DELTA-E(exp) data by point-charge model calculations.
