With the consumption of fossil resources, biomass materials have become a popular research topic. Natural vegetable oils, particularly Tung oil, are well-known to agricultural and forestry colleges/universities as best raw materials for producing biomass materials. The writers design an organic synthetic chemical experiment. Designed by specialty of Applied Chemistry and Materials Chemistry as a research-oriented practice, this experiment can be generated at agricultural and forestry colleges/universities, because the synthesis step is simple, easy to understand and master, and it covers key knowledge of related disciplines, including structural inorganic chemistry, organic synthesis chemistry, polymer chemistry, instrumental analysis, spectroscopy, etc. In the teaching practice, tutors can apply various measures, e. g. , key points analysis, literature review, experiment design and practice, group work, data processing and result analysis, to deepen students' understanding of theories, improve operational skills in chemical experiments, develop abilities to analyze and solve problems, foster research innovation, and enhance their awareness of environmental protection and social responsibilities.

In the past decade, coordination polymer as an interdisciplinary field has expanded rapidly and aUracted much interest of chemistry and materials. However, to the best of our knowledge, the coordination polymer is not involved in the inorganic chemistry experimental teaching up to now. Herein, on the base of our research, we introduce a synthetic experimental teaching of the synthesis and characterizations of the [Cu2I(DETRZ)]n coordination polymer constructed from 3,5-diethy-1,2,4-triazole ligand and [Cu4I4] cubane-like cluster. The foUowing experimental processes are included in this experiment : the synthesis and separation of triazole ligand, the solvothermal synthesis of coordination polymer, the single-crystal data coHection and solution, the crystal structure description, the powder X-ray diffraction, the infrared spectra analysis, thermogravimetric analysis, and so on. The coordination polymer experiment presented in this paper is simple and reliable, which combines the inorganic chemistry, organic chemistry and crystaHography, and effectively helps the undergraduates to learn the frontier of inorganic chemistry and coordination chemistry.
