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

In the present work, we report a detailed investigation of four supramolecular coordination complexes, Zn(Quino)(2)(CH3OH)(2) 2, Zn(QUino)(2)H2O3, Mn(Quino)(2) (CH3OH)(2) 4 and Ca(Quino)(2)(CH3OH)(2) 5, obtained from the self-assembling of Zn(II), Mn(11) and Ca(11) acceptors with the N-phenyl-4-hydroxyquinoline ligand donor QuinoH 1, possessing the beta,beta'-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 pi-pi stacking supramolecular synthon with the coordination preferences of metal ions has been used to construct coordination driven self-assembled "metallosupramolecular" architectures.
