Abstract

Abstract: By using solvated metal cations as structure‐directing agents, three new iodoargentates, namely, [Fe(DMSO)6 ][Ag6 I9 ]⋅DMSO (1 ), [Fe(H2 O)6 ][Ag15 I18 ] (2 ) and [Cd(DMSO)6 ][Ag8 I10 ] (3 ) (DMSO=dimethyl sulfoxide) have been solvothermally prepared and structurally characterized. The structures of compounds 1 and2 can be described as 1D chains constructed from the linkage of [Ag6 I9 ] and [Ag5 I11 ] building units, respectively. For compound 3, the [Ag10 I22 ] building blocks are directly interconnected to form a 2D [Ag8 I10 ] layer, which are further interconnected via intermolecular forces to generate a 3D supramolecular framework with 1D large channels occupied by [Cd(DMSO)6 ] 2+ cations. Interestingly, compounds 1 –3 exhibit an ion‐exchange behavior for the adsorption of a specific dye (methylene blue, MB). Moreover, photocatalytic experiments indicate that these iodoargentates can be considered as promising photocatalysts for the degradation of organic dye pollutants. Abstract : Producing a series : The assembly of AgI with Fe III or Cd II produces a series of iodoargentates showing efficient uptake and photocatalytic degradation of specific dye pollutants.
