Nakamura, Makoto -
The tin-119 Mossbauer effect was studied in complexes of dimethyltin dichloride, dibutyltin dichloride and tin (IV) chloride with nitrogen donors sudh as pyridine, phenanthroline, bipyridyl, quinoline, isoquinoline, β-naphthoquinoline or acridine. The data on the quadrupole splitting revealed that the alkyl groups in all the complexes of dialkyltin dichloride are situated in trans position to each other. The isomer shifts for the parent chloride and its complex decreased with an increase in electron-donating ability of R bonded to the tin atom, where R= n-C_4H_9, CH_3 or Cl, while a similar tendency was also found in the difference of the isomer shift between them. These results showed the dependence of the electron-donating ability of R on the group bonded to R.
