Ligand Structure Induced Diversification from Dinuclear to 1D Chain Compounds: Syntheses, Structures and Fluorescence Properties

Using the solvothermal method, we present the comparative preparation of [Zn2(Hfhba)4(phen)2] (1), [Zn2(Hfhba)4(2,2′-bipy)2] (2) and [Zn2(Hfhba)4(4,4′-bipy)2]n (3), where H2fhba is 5-fluoro-2-hydroxy-benzoic acid, phen is 1,10-Phenanthroline, 2,2′-bipy is 2,2′-Bipyridine, 4,4′-bipy is 4,4′-Bipyridine. Complexes 1–3 were characterized by elemental analysis, IR, UV–Vis spectroscopy, and X-ray single-crystal diffraction. Complexes 1 and 2 are two new dinuclear complexes and 3 is a 1-D polymer. Luminescent properties of 1–3 have also been studied.
