| 摘 要： | Five coordination compounds, namely Ni2(5-Fnic)2(H2 O)4](1), Ni(5-Fnic)(μ-5-Fnic)(H2 biim)]n(2), {Cd((μ-5-Fnic)2(H2 O)2]×4,4’-bipy}n(3), Pb2(μ-5-Fnic)2(μ3-5-Fnic)2(H2 O)2]n(4), and Pb(5-Fnic)2(4,4’-bipy)(H2 O)](5), have been constructed hydrothermally using 5-FnicH(5-FnicH = 5-fluoronicotinic acid), H2 biim(H2 biim = 2,2’-biimidazole), 4,4’-bipy(4,4’-bipy = 4,4’-bipyridine), NiCl2×6 H2 O, CdCl2×H2 O and PbCl2. The products were isolated as stable crystalline solids and were characterized by IR spectra, elemental analyses, thermogravimetric analyses(TGA), and single-crystal X-ray diffraction analyses. Structures of 1~5 range from discrete 0 D monomers(1 and 5) to 1 D coordination polymers(2 and 4) and 2 D metal-organic network(3). A broad structural diversity of 1~5 is guided by the type of the metal(Ⅱ) node and the introduction of auxiliary ligands. The magnetic(for 2) and luminescent(for 3~5) properties were also investigated and discussed.
