摘要

Three new mixed-ligand coordination polymers of Cu-II, namely, [Cu(Fbtx)(L1)(H2O)](n) (1), [Cu(Fbtx)(0.5)(HL2)(H2O)(2)](n) (2), and {[Cu(Fbtx)(1.5)(HL3)(H2O)]center dot H2O}(n) (3) [Fbtx = 2,3,5,6-tetrafluoro-1,4-bis(1,2,4-triazole-1-ylmethyl)benenze, H(2)L1 = terephthalic acid, H(3)L2 = trimesic acid, NaH(2)L3 = 5-sulfoisophthalic acid monosodium salt], were hydrothermally synthesized and structurally characterized by elemental analysis, IR spectra, and single-crystal and powder X-ray diffraction techniques. All the complexes have a two-dimensional (2D) coordination layer structure. Of these, 1 displays a planar 4(4)-sql structure whereas both 2 and 3 are highly undulated 6(3)-hcb nets. Moreover, their thermal stability and catalytic behaviors in the aerobic oxidation of 4-methoxybenzyl alcohol were also investigated as well. The results indicate that the benzene dicarboxylate ligands have an effective influence on the structures and catalytic properties of the resulting coordination polymers.
