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） A, V = 3437.2 （11 ） ,A Z = 4, C28H36Br2C12N604Zn, 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（/）. 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.展开更多

The crystal belongs to triclinic, space group , a=0.9861(2)nm, b=1.1930(2)nm, c=1.7140(3)nm, α =71.53(3)° , β =81.94(3)° , γ =75.56(3)° , V=1.848(6)nm3, Z=1, Dc=1.295g· cm- 3, F(000)=755, R1=0.0692, wR2=0.1845. The results show that the coordination geometry around copper? in the complex is slightly distorted four coordinated square planar geometry. The title complex was also characterized by elementary analysis, IR and TG. CCDC: 210089.展开更多

[Method] Soybean seedlings were treated by spraying the solution of conjugated compounds onto their leaves; and chromatography was employed to measure the contents of IAA-triadimenol and NAA-triadimenol in different parts of these soybean seedlings, through which to represent the mobility of the conjugates. [Result] Both the triadimenol and NAA-triadimenol could not transport basipetally; whereas IAA-triademenol was ambimobile. When sprayed with 0.5 mmol/L IAA-triadimenol, as much as 1.87 μg/(g·FW) IAA-triadimenol was detected in the roots of soybean seedlings 12 h later, which was higher than that in the stem [0.68 μg/(g·FW)]; while that decreased to 0.80 μg/(g·FW) in the seedlings sprayed with 0.5 mmol/L IAA-triadimenol and the same concentration of IAA. [Conclusion] IAA moiety of the conjugate could enhance the transport and accumulation of the fungicide towards the root via the IAA carriers.展开更多
