Abstract
Two 1D tpa complexes [Ag(tpa)(2‐apy)]n (1) and {[Ag(3‐apy)]·(tpa)·(H2O)}n (2) have been obtained from higher dimensional silver complex reaction systems and characterized. The complexes of 1 and 2 exhibit superprotonic conductivities with 3.27 × 10−2 S·cm−1 and 2.25 × 10−2 S·cm−1 respectively, in the same order of magnitude with that of the 1D 2,5‐tpa complex. The structures and topological analyses show the relative positions of substituents in neutral ligands affect the existence modes of tpa ligands, influencing the topological results and distributions of proton conduction sites, which do not affect the proton conductivities of the complexes dramatically. Instead, the dimensionalities of the complexes are closely related to the proton conductivities, indicating that in high humidity, abundant hydrogen‐bond networks are formed in pores and between main frameworks of the proton conductive compounds and influence the performance.
