Crystal Structure and Antifungal Activities of a New Zn(Ⅱ) Complex Based on Triadimenol
摘要:
A new Zn(Ⅱ) complex, [ZnL2Br2] (L=triadimenol) was synthesized by the reaction of ZnBr2 with the commercial fungicide of triadimenol, then characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The crystal structure shows that the complex [ZnL2Br2] crystallizes in orthorhombic, Pnam space group with a=11.263(2), b=8.4478(15), c=36.125(7) Ǻ, V=3437.2(11) Ǻ3, Z=4, C28H36Br2Cl2N6O4Zn, Mr=816.72, Dc=1.578 g/cm3, F(000)=1648, μ=3.236 mm-1, the final R=0.0388 and wR=0.0879 for 2399 observed reflections with I>2σ(I). The central metals adopt square plane coordination geometry. And intermolecular hydrogen bonds connect Zn(Ⅱ) into a one-dimensional chain. In addition, the title complex and triadimenol were screened for antifungal activities against four selected fungi using the mycelial growth rate method. The results indicate that the complex synthesized shows better antifungal activities than the ligand triadimenol.
