一维链状酰基吡唑啉酮配合物Zn(C26H15N3O2Cl)2的合成、晶体结构及热稳定性

A one-dimensional chain complex bis{4-(Z)-(4-chlorophenylamino)(2-furyl)methylene]-3-methyl-1-phenylpyrazol-5-onato}zinc(Ⅱ) Zn(C₂₆H₁₅N₃O₂Cl)₂ has been synthesized. Its structure was characterized by elemental analysis, IR, UV, thermal analysis and X-ray diffraction single crystal structure analysis. The title complex crystallizes in triclinic system, space group P1 with a=0.903 58(18) nm, b=1.359 8(3) nm, c=1.757 0(4) nm; α=102.42(3)°, β=101.24(3)°, γ=109.2(4)°, V=1.906 3(10) nm³. The final R factors are R=0.051 3 and wR=0.133 9. The zinc atom is four-coordinate involving two oxygen atoms and two nitrogen atoms forming a distorted tetrahedral geometry. The intermolecular hydrogen bonds C-H…N, C-H…Cl, C-H…π, together with intramolecular π…π stacking in the large congujate system, leading to the formation of a one-dimensional supramolecular chain. The results of TG-DTA analysis show that the title complex was stable under 323 ℃. CCDC: 299690.
