Incorporating Rare Earth Metal Complexes and Conjugated Organic Cations into Polymeric Iodoargentate: Structures and Properties of Two Hybrid Iodoargentates

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–...

Description
Summary: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.
