(4) (H2dba = 2,5-dihydroxy-p-benzenediacetic acid, bpy = 2,2′-bipyridine, phen = 1,10-phenanthroline) have been prepared via solvothermal
method and characterized by single-crystal X-ray diffraction, infrared spectroscopy, elemental analysis and powder X-ray diffraction.
1 and 2 possess 1D infinite chain structures. Complex 3 exhibits a mononuclear structure. Complex 4 owns binuclear symmetry
units, which were bridged via the dba ligands forming a 2D framework. The fluorescence properties of 1–4 have been studied. |
