Abstract: Hydrothermal reactions of transition metal(Ⅱ) salts with 3-fluorophthalic acid (H2Fpht) and 1,10-phenanthroline (phen) afforded five complexes, [M(Fpht)(phen)(H2O)3]·H2O (M=Ni 1, Co 2), [Cu(Fpht)(phen)(H2O)]·H2O (3) and [M(Fpht)(phen)(H2O)]·H2O (M=Zn 4, Cd 5). The complexes were characterized by single crystal X-ray diffraction, elemental analyses, IR spectroscopy, thermogravimetric analyses and fluorescence spectra. Complexes 1 and 2 are mononuclear molecules. Ni(Ⅱ) or Co(Ⅱ) ion is eight-coordinated by one O atom from Fpht ligand, two N atoms from phen and three O atoms from water molecules in distorted octahedral coordination geometry. Complex 3 possesses a zigzag 1D chain structure. Cu(Ⅱ) ion is five-coordinated by two O atoms from two Fpht ligands, two N atoms from phen and one O atom from water molecule in square-pyramidal coordination geometry. Complexes 4 and 5 show 1D helical chain structure. Zn(Ⅱ) or Cd(Ⅱ) ion is eight-coordinated by three O atoms from two Fpht ligands, two N atoms from phen and one O atom from water molecule in distorted octahedral coordination geometry.
