一种新型不对称三足四胺席夫碱锌(Ⅱ)配合物的合成、结构及杀菌性能研究(英)

A new tripodal complex ZnL](ClO₄)₂ (C₂₆H₃₁Cl₂N₇O₈Zn) was synthesized by Schiff base condensation of 2-aminoethyl-bi(3-aminopropyl)amine with 2-pyridinecarbaldehyde in the presence of Zn²⁺ and characterized by X-ray diffraction and ES mass spectral analysis. It crystallized in the Monoclinic system, space group P2₁/c with a=1.088 5(4) nm, b=1.614 6(6) nm, c=1.7830(5) nm, β=94.405(2)°. Z=4, R₁=0.092 9, wR₂=0.175 8. Zn atom rendered six-coordinate in a trigonal antiprism geometry. The complex was valued for its antimicrobial activity against bacterial strands using the agar diffusion method. It was found to be active against the four test bacterial organisms. CCDC: 231275.
