摘要
Abstract
Crystal field theory stands as a cornerstone in coordination chemistry and poses a pivotal challenge in undergraduate inorganic chemistry education.Leveraging recent advancements in the synthesis of nickel macrocyclic coordination compounds,we introduce a highly adaptable and multifaceted comprehensive experiment.Students engage in synthesizing a series of nickel complexes,observing their colors,and analyzing their infrared absorption spectra,UV-visible absorption spectra,and effective magnetic moments.By integrating classroom instruction with literature review,students deduce the ligand composition and central ion crystal field configuration of the complexes.Spanning 8 class hours,this experiment amalgamates theoretical knowledge and experimental skills across inorganic,analytical,and physical chemistry domains.It exhibits conspicuous experimental phenomena,excellent reproducibility,low cost,and high safety standards.Moreover,it extensively cultivates students'analytical prowess in tackling real-world problems within a problem-oriented learning framework,thereby enhancing their fundamental chemical literacy.关键词
