Synthesis and structural studies of quinolone-based Zn(II), Mn(II) and Ca(II) complexes involving supramolecular interactions

Abstract

In the present work, we report a detailed investigation of four supramolecular coordination complexes, Zn(Quino)₂(CH₃OH)₂ 2, Zn(Quino)₂H₂O 3, Mn(Quino)₂(CH₃OH)₂ 4 and Ca(Quino)₂(CH₃OH)₂ 5, obtained from the self-assembling of Zn(II), Mn(II) and Ca(II) acceptors with the N-phenyl-4-hydroxyquinoline ligand donor QuinoH 1, possessing the β,β′-diketonate moiety. The structure of the supramolecular arrangement of the isolated complexes have been investigated by single crystal X-ray crystallography. The synthetic N-phenyl quinolone-linker that forms a π–π stacking supramolecular synthon with the coordination preferences of metal ions has been used to construct coordination driven self-assembled “metallosupramolecular” architectures.
