摘要
A series of silver coordination polymers (CPs) have been synthesized through self-assembly of three pyridinecarboxylic acid hydrazide (p-, m-, o-position) ligands with silver clusters (named Ag1-iah, Ag2-iah, and Ag3-iah). These silver CPs show different one- and two-dimensional topologies including cross-helical chains, planar network, and parallel helical chains for Ag1-iah, Ag2-iah, and Ag3-iah, respectively. The combination of experimental and computational results reveals the critical role in the space distribution of the coordination site of silver clusters and ligands in controlling the silver CPs’ dimensionality and packing arrangement and modulating the optical properties and stability. Luminescent investigations reveal that Ag3-iah can selectively detect dichloromethane or trichloromethane in tetrachloromethane. These silver CPs provide a good model to study the influence of the space distribution of the coordination site of ligands on their packing arrangement and properties.
