The optimal condition of the synthesis was explored by investigating the effect on the reaction and a yield of 53.68%. The ligand was characterized by melting point determination, elemental analysis, IR, NMR, and MS spectra analysis. The single-crystal X-ray diffractometer was adapted to analyze the ligand structure, and the unit cell datas indicate that crystal of 2-(5-methyl-3-pyrazoles) pyrazole?acetamide ligand belongs to three inclined crystal department and its space group is P-1. The crystal cell parameters were presented as followed : a = 5.1170 (8) ?, b = 8.2077 (13) ?, c = 13.689 (2) ?, V = 541.91 (15) ?3, Z = 2, R2 = 0.0617, wR2 = 0.1678. 【KEYWORDS】Pyrazole?acetamide Ligand;Synthesis;Characterization;Crystal structure 目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc292464431 1 引言 PAGEREF _Toc292464431 \h 5 HYPERLINK \l _Toc292464432 1.1 研究意义 PAGEREF _Toc292464432 \h 5 HYPERLINK \l _Toc292464433 1.2 国内外研究现状 PAGEREF _Toc292464433 \h 5 HYPERLINK \l _Toc292464434 1.2.1 吡唑酰胺类化合物的发展历程 PAGEREF _Toc292464434 \h 6 HYPERLINK \l _Toc292464435 1.2.2 吡唑酰胺类配合物的研究现状 PAGEREF _Toc292464435 \h 6 HYPERLINK \l _Toc292464436 1.2.3 吡唑类化合
