Me4NO2C-SO3H.2SnPh3Cl and enH2O2C-SO3.SnPh3Cl are obtained on allowing Me4NO2C-SO3H and enH2O2C-SO3 to react with SnPh3Cl in respectively mixed solution (ethanol/water) or ethanolic solution in specific ratios. Their infrared studies have been carried out and structures as dimers, suggested when hydrogen bonds are involved.
