Alkoxido-bridged binuclear copper(ii) complexes derived from aminoalcohols – useful building blocks in designing coordination polymers with a rich structural variety

Abstract

The reactions of copper(II) salts with aminoalcohols frequently afford alkoxido-bridged dimers. Neutral (e.g. bis(4-pyridyl) derivatives) or anionic divergent ligands (e.g. polycarboxylate anions, polycyanido-metallates) are employed as spacers. In this paper, a rich variety of structures are reviewed, emphasizing the role played by the denticity of the aminoalcohols and of the linkers, as well as by the accompanying anions, in the network topology. The involvement of coordinative and non-covalent bonds (π–π stacking, argentophilic/aurophilic, π⋯Hg interactions, hydrogen bonds) in sustaining the solid-state architectures is also discussed.
