Covalent post-assembly modification in metallosupramolecular chemistry

This review examines the growing variety of covalent reactions used to achieve the post-assembly modification of self-assembled metallosupramolecular complexes.

Metallosupramolecular Chemistry of AgI Complexes with Azobis(2-pyridine) and its Derivatives

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 5.82 Å. 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.
