Abstract

The study of the interactions between (Me4N)2(C2O4)SnPh2•H2O and SnCl2•2H2O in EtOH has yielded a trinuclear adduct which Mössbauer study has allowed to choose (Me4N)2(C2O4)2SnCl2•2SnPhCl3 rather than (Me4N)2(C2O4)2SnPh2•2SnCl4 for formula, the oxalate anion behaving as a bichelating ligand, the environment around the tin (IV) centre being octahedral.
