Magnetic, spectroscopic and structural properties of a copper cyclic compound

Abstract

A new compound [Cu(oda)(pmal)(H₂O)]₂·4H₂O assembled from phenylmalonic acid (H₂pmal), 4,4ʹ-diaminodiphenyl ether (oda) and Cu(II) was synthesized under mild conditions in solution. Its structure was determined by X-ray single crystal diffraction. The structure is characteristic of neutral cyclic dimeric molecules which further aggregate through hydrogen bonds and π–π interactions to form a 3-D supramolecular network. The compound was also characterized by UV–vis, TG-DSC, XRD, ESR and magnetic susceptibility.
