                                摘要:
                                Reaction of Cu(II) with an asymmetric semi-rigid organic ligand 4-(1H-1, 2, 4-trizol-1-ylmethyl) benzoic acid (HL), yielded five compounds, [Cu0.5L](n) (1), [Cu(HL)(2)Cl-2](n) (2), [Cu(HL)(2)Cl-2(H2O)] (3), [Cu(L)(2)(H2O)](n) (4) and [Cu(L)(phen)(HCO2)(n) (3), which have been fully characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. As for compounds 1, 2 and 5, Cu(II) is bridged through HL, Cl-, and formic acid, respectively, featuring 1D chain-structure. In compound 3, Cu(II) with hexahedral coordination sphere is assembled through hydrogen-bonding into 3D supramolecular framework. In compound 4, 1D chain units -Cu-O-Cu-O are ligand-bridged into a 3D network. All compounds were tested on fungi (Fusarium graminearum, Altemaria solani, Macrophoma kawatsukai, Alternaria alternata and Colletotrichum gloeosporioides). Compound I exhibits a better antifungal effect compared to other compounds. An effect of structure on the antifungal activity has also been correlated. (C) 2014 Elsevier Inc. All rights reserved.
