Two new polymeric iodoargentate hybrids induced by rare earth metal complexes and conjugated organic cations, {[Er(DMF) 8 ][Ag 6 I 9 ]} n ( 1 ) and [(MMP)(AgI 2 )] n ( 2 ) (MMP = 1‐methyl‐4‐methylpyridinium) were obtained by the routine synthetic reaction and structurally determined. In compound 1 , a (Ag 6 I 9 ) n 3 n – chain is defined by edge‐sharing Ag 6 I 12 units, and in 2 , the (Ag 2 I 4 ) n 2– chains are constructed by edge‐sharing AgI 4 tetrahedra. C–H ··· I hydrogen bonds between cations and iodoargentate polyanions contribute to their structural extension from 1D to a 2D layer (for 1 ) and a 3D network (for 2 ). The UV/Vis spectra indicate that compared with 2 , compound 1 exhibits a narrower adsorption scope with an onset at about 360 nm, and it has a much wider bandgap of about 3.50 eV.
