Three multinuclear metal–organic coordination compounds based on 8-hydroxyquinoline derivative: Syntheses, structures and fluorescence properties
2015
Abstract By taking advantage of the synthetic 8-hydroxyquinoline derivative, (E)-2-[2-(4-chlorophenyl)vinyl]-8-hydroxyquinoline ( HL ), three new metal–organic coordination compounds [Zn 3 L 6 ] ( 1 ), [Cd 3 L 6 ] ( 2 ) and [Cu 2 L 4 ] ( 3 ) have been obtained by solvothermal or solution processing methods and structurally characterized. Single crystal X-ray diffraction analysis revealed that complexes 1 and 2 have similar ‘V’-type trinuclear structures. Different from complexes 1 and 2 (trinuclear structure), complex 3 displays dinuclear structure. The effects of central metals and reaction solvents on the structures of complexes 1 – 3 have been discussed. Furthermore, thermogravimetric analysis and solid state fluorescence of ligand HL , 1 – 3 were investigated.
