![عکس صفحه اول مقاله: Synthesis and structural studies of novel Cu(II) complexes with hydroxy derivatives of benzo[b]furan and coumarin Synthesis and structural studies of novel Cu(II) complexes with hydroxy derivatives of benzo[b]furan and coumarin](/preview/png/1334761.png)
A series of new Cu(II) complexes with the hydroxy derivatives of benzo[b]furan and coumarin have been electrochemically synthesized. The geometry of the metal–ligand interaction has been described using the single crystal X-ray diffraction method and X-ray absorption spectroscopy. Two ligands are bonded to the metal cation via the acetyl and deprotonated hydroxyl O atoms. The centrosymmetric coordination polyhedron of Cu(II) exhibits a square-planar geometry (CuO4), with both ligands coordinating in the chelating mode.
The Cu(II) cation is four- coordinated in five complexes with the hydroxy derivatives of benzo[b]furan and coumarin. The complexes have been studied by the XAFS analysis and the X-ray crystallography.Figure optionsDownload as PowerPoint slideHighlights
► Electrochemical synthesis of Cu(II) complexes with hydroxy derivatives of benzo[b]furan and coumarin.
► Metal–ligand interactions were studied by X-ray crystal structure analysis and X-ray absorption spectroscopy.
► Five mononuclear complexes were obtained; four with benzo[b]furan ligands and one with hydroxycoumarin.
► In all the complexes Cu(II) is chelated by two anionic ligands and the CuO4 environment shows a square-planar geometry.
