| Abstract: The Ag(Ⅰ) complex of tebuconazole [AgL2]NO3(L=(RS)-1-(4-chloro-phenyl)-4,4-dimethyl-3-(1,2,4-triazole-1-ylmethyl)pentan-3-ol), tebuconazole) was synthesized and characterized by elemental analysis, IR, single crystal X-ray diffraction. The crystal is in the monoclinic system, space group C2/c, with cell parameters: a=3.698 9(7) nm, b=0.902 8(2) nm, c=1.122 8(2) nm, β=103.66(13)?, V=3.643 3(13) nm3, Dc=1.432 g·cm-3, Z=4, F(000)=1 624, μ=0.748 mm-1. The metal atoms are bridged by L to form coordination chains, which are linked by O-H…N hydrogen bonds to form a two-dimensional structure. The sterilization/disinfectant effect of tebuconazole and its silver complex to the Gibberella nicotiancola and Apple black fruit rot and the regulatory role to wheat growth were studied. The results show that [AgL2]NO3 is ineffective to the germination and growth on wheat, while it is active to inhibit Gibberella nicotiancola and Apple black fruit rot. CCDC: 917713. | |
