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
