Novel layered sulfides of tin: synthesis and structural characterization of Cs4Sn5S12·2H2O and Sn5S12(N2C4H11)2(N4C10H24)

Abstract
Framework compositions [Sn5S12]4– have been synthesized hydrothermally in the presence of triethylenediamine (Dabco) and caesium, respectively; the cations are accommodated between the sheets with orientation relationships suggestive of a templating mechanism and their crystal structures have been determined.
