| Abstract: | Two series of diorganotin(IV) dialkyldithiophosphates, RR′Sn{SSP(OR″)2}2](R = Me or Et; R′= Ph; R″ = Et, Prn, Pri or Bun) and RR′Sn(Cl){SSP(OR″)2}] (R = R′= Me, Et or Ph; R″ = Ph; R″ = Et, Pri or Bun) were prepared and characterised by i.r. and NMR (1H, 13C, 31P, 199Sn) spectroscopy. The NMR data indicate five and six coordinate geometries for RR′Sn(Cl){SSP(OR″)2}] and RR′Sn{SSP(OR″)2}2] complexes, respectively. The chloro complexes showed 2J (PSn) whereas such couplings were not observed in the spectra of RR′Sn{SSP(OR″)2}2]. |
