Study of the Interaction of Trimethyltin(IV) Chloride with N,N,N’,N’-tetraethylethylenedimanine in Reference to Marine Environmental Pollution

Abstract

The interaction of trimethyltin(IV) with N,N,N’,N’-tetraethylethylenediamine (Et₄en) was investigated potentiometrically. The hydrolysis constants of trimethyltin(IV) species and formation constants of the amine complexes are determined. The formation constant of the complex is high, which may suggest to use Et₄en as an antidote for triorganotin(IV) poisoning, the main source of marine environmental pollution. The effect of solvent dielectric constant of the medium and temperature on the complex formation equilibria was investigated.
