Investigations on template CrO42-/Cr2O72- influence in forming series of silver-chalcogenide clusters

Abstract

Three new silver-chalcogenide clusters protected by naphyl ligands are described in this work, namely [Ag14(SCH2C10H7)6(CF3COO)8(DMAc)6] (1), [Ag30(SCH2C10H7)18(CrO4)2(DMAc)2 (CF3COO)8] (DMAc = Dimethylacetamide) (2) and {Ag12(SCH2C10H7)6(CF3COO)4(CH3CN)6(Cr2O7)}n (3). Their crystal structures were studied by X-ray crystallography, and they show hollow-core-shell (1), template-core-shell (2) and 1D infinite (3) structures respectively. Moreover, the luminescent property of cluster 1 was investigated, which showed interesting characteristics of thermochromism variation from red to bright yellow. Moreover, the chromate ions as templates in forming silver clusters were also proved through series of experiments in preparing compounds 2 and 3, which could be looked as the derivatives of the cluster 1.
