摘要

A Fe(III)-iodoargentate hybrid [Fe(DMSO)6]Ag10I13 (1) (DMSO = dimethyl sulfoxide) was prepared using a solvated Fe(III) complex cation [Fe(DMSO)6]3+ formed in-situ as the template under solvothermal conditions. It consists of a [Fe(DMSO)8]3+ complex cation, and a 2-D [Ag10I13]n3n‒ layered anion. The 2-D [Ag10I13]n3n‒ anion is composed of ten crystallographically independent AgI4 tetrahedral units through corner- and edge-sharing, which contains large circles of Ag7I7 with cross sectional dimensions of 7.285 Å × 8.592 Å. Compound 1 exhibits rapid photocurrent response with steady current density of 4.83 µA·cm− 2 under visible light irradiation. It shows high photocatalytic activities in the degradation of MB with degradation ratio of 98.8% after light irradiation of 60 min.
