Structural diversity of Cu(I), Ag(I) and Cu(II) coordination polymers with the ligand ethanediyl bis(isonicotinate)

Abstract

This thesis reports the synthesis of the ligand ethanediyl bis(isonicotinate), L, as well as the building of coordination polymers based on L and CuI, AgI and CuII salts. Chapter A gives an overview on coordination polymers, their syntheses, structures, and applications. It describes the use of bidentate ligands with N,N’-donors with silver and copper cations for the building of such metal-organic frameworks. Chapter B-I discusses the synthesis of the ligand ethanediyl bis(isonicotinate), L, and presents its characterizations and its crystallographic structure. Chapter B-II describes coordination polymers obtained from L and CuCl. It is focused on the importance of the crystallization solvent, since two different compounds appear according to the chosen crystallization solvent. Chapter B-III is devoted to the study of silver(I) coordination polymers based on L and silver salt. The numerous obtained silver coordination polymers allow finding some rules concerning the crystallization solvent influence or the counter ion influence. Chapter B-IV presents some copper(II) coordination polymers build up with L and copper nitrate or perchlorate. With these compounds, the behaviour of the ligand L towards more “rigid” cations was studied. Chapter C summarizes the related works, presents the outlooks to this project and especially the possible applications for the synthesized metal-organic frameworks.
