Abstract
In our effort to systematically investigate the influences of ligand spacers and terminal groups on the Ag/I inorganic framework with large organic cation SDAs (structure-directing agents) ([Et3N(CH2)4NEt3]2+, [Et3N(CH2)6NEt3]2+, and [Me3N(CH2)6NMe3]2+), three silver(I) coordination polymers, {[Et3N(CH2)4NEt3][Ag4I6]}n (1) {[Et3N(CH2)6NEt3][Ag5I7]}n (2), and {[Me3N(CH2)6NMe3][Ag4I6]}n (3), have been synthesized in polar organic solvent. 1−3 all consist of one-dimensional polymers that could be described as edge-sharing AgI4 tetrahedrons. Electrostatic interactions between organic countercations and inorganic moieties are presented and contribute to the crystal packing. The structural differences among 1−3 show the influences of the spacers and substituents of SDAs on the linkage modes of AgI4 tetrahedrons. All compounds were further characterized with IR spectra, elemental analysis, thermal measurements, fluorescence analysis, and optical limiting measurements.
