Abstract

The hydrolysis of Sn(OAmt)2(acac)2 (TTA) leads to sols, gels or precipitates made of tin oxohydroxo polymers, surface capped with residual organic groups, which are mainly acac ligands. The residual acac/Sn ratio decreases when the hydrolysis ratio H increases. For a given H, the observed gelation-precipitation behavior and the BET surface areas of the resulting xerogels strongly depend on the nature of the solvent.
