Azacrown ether–copper(ii)–hexanoate complexes. From monomer to 1-D metal organic polymer

Author affiliations

Abstract

The synthesis and characterisation of two new Cu(II)-hexanoate-azacrown ether species are described. The first monomeric complex is a “classical” macrocyclic Cu(II) complex with two monodentate axially coordinated carboxylates serving as counterions. The second is an adduct of the former complex with the copper(II) hexanoate paddlewheel dimer, Cu2(hexanoate)4, forming an infinite 1-D chain of alternating monomer–dimer units. The electronic and magnetic properties of both species are discussed based on UV-vis, IR, X-ray and EPR studies combined with the DFT calculations. The UV-vis titration results prove that complex 1 and the polymeric species 2 are in equilibrium in toluene solution.
