摘　　要：在THF体系中,设计并成功地合成了两种具有平面结构的三嗪类衍生物2,4-二(3,5-二甲基吡唑)-6-二乙胺基-1,3,5-三嗪(简写为Bpz*eaT)和2,4,6-三(3,5-二甲基吡唑)-1,3,5-三嗪(简写为Tpz*T)化合物,并以此为配体,在不同的温度下合成了3种新型配合物Co(Bpz*eaT)Cl2(1),[Co(Bpz*T-O)2]·(COO)2·H2O(2),[Co(Mpz*T-O2)2(H2O)2]·3H2O(3).通过元素分析、红外光谱、紫外光谱、X射线粉末以及X射线单晶衍射方法对配合物进行了表征,并分析了其光谱及结构特征.此外,还对三嗪衍生物在高温条件下发生的原位反应进行了讨论.Two planar tridentate pyrazole-triazine（like-scorpionate） compounds, 2,4-bis（3,5-dimethylpyrazol-1-yl）-6-diethylamino-1,3,5-triazine （bpz＊eaT） and 2,4,6-tris（3,5-dimethyl-pyrazol-1-yl）-1,3,5-triazine（Tpz＊T） were designed and synthesized successfully in the THF system. Three novel complexes Co（bpz＊eaT）Cl2 （1）, [Co（Bpz＊T-O）2] （COO）2·H2O （2） and [Co（Mpz＊T-O2）（H2O）2]（OH）2.2H2O （3） were synthesized by the reaction of metal salt （COCl2·6H2O or Co（CH3COO）2 ~ 4H20）, and the ligands in the system of the acetonitrile or mixed solution at different temperature. The complexes were characterized by elemental analysis, IR spectrum, UV spectrum, X-ray powder and X-ray monocrystal diffraction technology. In addition, the structural characters and spectrum characters of the three complexes were analyzed in detail. Furthermore, the in situ chemical reaction of the triazine derivatives, which is under high temperature, has been discussed.
