Abstract
Four silver thiolate clusters, [H3O]·[(Ag3S3)(BF4)@Ag27( t BuS)18(hfac)6H2O]·H2O (1; hfac = hexafluoroacetylacetone), [(Ag3S3)(CF3CO2)@Ag30( t BuS)16(CF3CO2)9(CH3CN)4]·CF3CO2·4CH3CN (2), [(Ag3S3)(MoO4)@Ag30( t BuS)16(CF3CO2)9(CH3CN)4]·2CH3CN (3), and [(Ag3S3)(CrO4)@Ag30( t BuS)16(CF3CO2)9(CH3CN)4]·4CH3CN (4), were isolated, which have the similar nest-like structure assembled by a [Ag3S3]3- template together with one of BF4-, CF3CO2-, MoO42- and CrO42- anions. Interestingly, the solid-state emissions of 2-4 are dependent on the templating anions and are tunable from green to orange and then to red by changing templates from CF3CO2- to MoO42- and to CrO42-, which maybe correlate to the charge transfer between these templates to metal atoms. This work helps to understand the templating role of hetero anions and the relationship between structure and properties.
