Abstract

By following a new synthetic approach, which is based on the in situ formation of a basic medium by the reaction between the strong base Sb(V)S-4(3-) and the weak acid H2O, it was possible to prepare three layered thioantimonate(III) compounds of composition [TM(2,2'-bipyridine) (3)][Sb6S10] (TM=Ni, Fe) and [Ni(4,4'-dimethyl-2,2'-bipyridine) 3][Sb6S10] under hydrothermal conditions featuring two different thioantimonate(III) network topologies. The an timony source, Na3SbS4 center dot 9H(2)O, undergoes several decomposition reactions and produces the (SbS3)-S-III species, which condenses to generate the layered anion. The application of transition-metal complexes avoids crystallization of dense phases. The reactions are very fast compared to conventional hydrothermal/solvothermal syntheses and are much less sensitive to changes of the reaction parameters.
