Two Ag (I) photoresponsive metal–organic complexes have been constructed from viologen derivatives 1, 1″-[1, n-phenylene-bis(methylene)]bis-4, 4′-bipyridinium-bisbromide (n = 2 and 3) cationic ligands and silver bromide upon slow self-assembly at room temperature. They are characterized by single crystal X-ray diffraction, powder X-ray diffraction, thermal gravimetric analysis (TGA), UV–vis, IR and ESR spectra. Compound 1 is a 3D folding framework and compound 2 contains a 1D inorganic chain constructed by (AgBr3)2 − polyhedral units. In addition, the photochromic behaviors of compounds 1 and 2 were also investigated, and they show different and obvious fast photoresponse rate under sunlight.
