A new low‐dimensional benzyl viologen/iodoargentate hybrid, [(BV) 2 (Ag 5 I 9 )] n ( 1 ) (BV 2+ = benzyl viologen) was prepared. In 1 , (Ag 6 I 9 ) n 2– chain exhibits a new type of one‐dimensional chain constructed from vertex‐sharing of Ag 5 I 10 units, and its two‐dimensional layer structure was constructed from C–H ··· I hydrogen bonds. Strong luminescence at 404 nm can be detected in 1 . DFT calculation suggests that 1 displays a reduced bandgap, which is led by a more dispersed LUMO band of BV 2+ compared with M V 2+ in [ M V(Ag 2 I 4 )] n .
