Metallosupramolecular chemistry of AgI complexes with azobis(2-pyridine) and its derivatives

Abstract

Reactions of three azobis(2-pyridines) with silver salts lead to 1D coordination polymers whose structures have been determined by single crystal X-ray crystallography. The azobis(2-pyridines) consistently act as di-bidentate ligands that bridge silver atoms separated by distances ranging from 5.49 to 5.82A ° . Two of the coordination polymers consist of chains in which consecutive bridging ligands are orthogonally oriented. The other polymer has a considerably more complicated structure due to the more intimate involvement of the trifluoroacetate counteranions, which also act as bridges between silver centres.
