摘要：

介绍南京大学为“第10届全国大学生化学实验邀请赛”设计的“无机及分析化学实验试题”，即“配合物[Ni(Me3en)(acac)]BPh4的合成及其溶剂/热致变色行为研究”实验中有关溶剂/热致变色行为研究部分实验实施过程、结果及其有关问题探讨内容等。以所展示的详细直观的溶剂/热致变色实验现象启发学生探讨和解释其溶剂/热致变色的原理，总结其溶剂/热致变色规律，让学生直观认识配合物的结构决定其性质的涵义，培养学生分析、判断、归纳、总结的能力以及批判性思维能力。

关键词: Ni(Ⅱ)配合物, 溶剂/热致变色及原理, 问题分析与探讨

Abstract:

This paper mainly introduces the inorganic and analytical chemistry laboratory project, the synthesis of the complex [Ni(Me3en)(acac)]BPh4 and the solvato/thermochromic behavior, designed by Nanjing University for "The 10th National Undergraduate Chemistry Laboratory Tournament". This paper mainly deals with the experiment implementation process, results and related issues of the solvato/thermochromic behavior in the experiment. In the paper, the detailed and intuitive experimental phenomena inspire students to explore and understand the mechanism. The law of solvato/thermochromic behavior is summarized, which allows students to intuitively understand that the structure of complexes determines their properties. In the process, students can develop the ability of analysis, judgment, induction, summarizing and critical thinking.

Key words: Ni(Ⅱ) complex, Solvato/Thermochromic behavior and mechanism, Analysis and discussion of experimental results
