| 中文摘要: |
| 以取代肉桂酸甲酯与对甲氧基苯肼为原料，合成得到1，5-二芳基-3-吡唑烷酮衍生物，利用溶剂挥发法得到 5-(3，4-二甲氧基苯基)-1- 对甲基苯基-3-吡唑烷酮化合物的单晶，对其进行元素分析、核磁表征和X-射线单晶衍射分析。晶体结构分析结果表明:该晶体为三斜晶系、P-1空间群，属于五元半椅式结构，晶胞参数为:a=9.429(19)Å；，b=10.107(2)Å；，c=10.848(2)Å；，α=96.50(3)°，β=111.60(3)°，γ=114.43(3)°。 |
| 英文摘要: |
| To replace the methyl cinnamate and p-methoxy phenylhydrazine as raw material, 1, 5-diaryl-3-pyrazolidinone derivatives were synthesized. A single crystal of 5-(3, 4-dimethoxyphenyl)-1-p-methylphenyl-3-pyrazolidinone compound was obtained by a solvent evaporation method. Its elemental analysis, nuclear magnetic characterization and X-ray single crystal diffraction analysis were carried out. The crystal structure analysis results show that the crystal is triclinic P-1 space group, which belongs to five-element half-chair structure. The unit cell parameters are: a=9. 429(19)Å , b=10. 107(2)Å , c=10. 848(2)Å , α=96. 50(3)°, β=111. 60(3)°, γ=114. 43(3)°。 |
