本文用氢氧化铈(Ⅳ)在二氧六环中,通入干燥的HCl气体,得到了热稳定性较好的四或五氯化二氧环合铈(Ⅳ)配合物-Ce(C_4H_8O_2)_4Cl_4或HCe(C_4H_8O_2)_4Cl_5。并将五氯化二氧六环合铈(Ⅳ)配合物与不同的含氮化合物配合,合成了一些新的五氯化二氧六环合铈铵盐配合物(HL)Ce(C_4H_8O_2)_xCl_5(L=8-羟基喹啉、咪唑、邻啡啰啉、吡啶、氮杂菲、吩嗪;x=1,2,3,4)。上述配合物通过元素分析、红外光谱、紫外光谱、热分析和电子能谱进行了鉴定。研究了不同的含氮化合物对四价铈氯化物热稳定性的影响。
In this paper, the dry HCl gas is introduced into dioxane by using cerium (IV) hydroxide to obtain the complex of Ce (C_4H_8O_2) _4Cl_4 or HCe (C_4H_8O_2) _4Cl_5. Some new complexes of Ce (C_4H_8O_2) _xCl_5 with cerium ammonium chloride hexahydrate (Ce) have been synthesized by the combination of different complexes of cerium (Ⅳ) (L = 8-hydroxyquinoline, imidazole, o-phenanthroline, pyridine, phenanthroline, phenazine; x = 1, 2, 3, 4). The above complexes were identified by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy, thermal analysis and electron spectroscopy. The effects of different nitrogen compounds on the thermal stability of tetravalent cerium chloride were investigated.
