| Abstract: | Two new polymeric iodoargentate hybrids induced by rare earth metal complexes and conjugated organic cations, {[Er(DMF)8][Ag6I9]}n ( 1 ) and [(MMP)(AgI2)]n ( 2 ) (MMP = 1‐methyl‐4‐methylpyridinium) were obtained by the routine synthetic reaction and structurally determined. In compound 1 , a (Ag6I9)n3n– chain is defined by edge‐sharing Ag6I12 units, and in 2 , the (Ag2I4)n2– chains are constructed by edge‐sharing AgI4 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. |
