Abstract  

The compounds [(LR2Sn)2O] {R=CH3 (Me), n-C4H9(Bn); L=C6H5CH(OH)COO}were studied by thermogravimetric and differential scanning calorimetry in a dynamic atmosphere of helium. The thermal decomposition mechanisms are similar for both compounds and occur in two consecutive steps. The TG curves of the complexes suggest the liberation of the ligand L in the first step, with probable formation of a tin oxide R2SnO intermediate. At the end of the second step free tin is obtained in accordance with the stoichiometry of the related compounds. An inverse relation betweenΔHfusion and solubility of the compounds suggests a polymeric structure for the compound with Bn ligand in relation to the compound with M ligand.
