Coordination polymers (CPs) display great potential for the development of highly active photocatalysts. Herein, we report the fabrication of a highly crystalline CP, [Ag2BTT]n (BTT=benzene‐1,2,4,5‐tetrathiol). The crystal structure of [Ag2BTT]n was resolved and its performance for photocatalytic oxidation of thioanisole was explored. [Ag2BTT]n is highly active and selective for the photo‐oxidation of sulfides to sulfoxides under mild conditions, that is, in air, at room temperature and in the absence of a sacrificial reagent, co‐catalyst or redox mediator. A highly crystalline coordination polymer, [Ag2BTT]n (BTT=benzene‐1,2,4,5‐tetrathiol), was designed and its crystal structure resolved by synchrotron radiation powder X‐ray diffraction. [Ag2BTT]n exhibits a low hole‐electron recombination rate, strengthened transfer efficiency of photoexcited charges and abundant catalytic active sites, which make it highly active and selective for the photo‐oxidation of sulfides to sulfoxides under mild conditions, i. e., in air, at room temperature and in the absence of a sacrificial reagent, co‐catalyst or redox mediator.
