中文摘要：

结合SO2-4/Pb2＋沉淀置换法和二氧六环沉淀法得到了一种类长方体的块状Al13硝酸盐晶体,并与乙醇-二氧六环沉淀法制得的八面体构型的Al13盐酸盐晶体及文献已报道的正四面体的硫酸盐晶体进行了分析比较.X射线衍射图谱结果表明,Al13盐酸盐为单斜晶系,Al13硝酸盐为正交晶系.阴离子的种类不同会导致Al13晶体的晶格尺寸、晶间间距、晶体构型和溶解度等的不同,可以从阴离子的角度来研究Al13的结构和性质.

英文摘要：

Al13 nitrate crystal, whose configuration was similar with cuboid, was synthesized by SO2-/Pb2＋ pre- cipitation-exchange method combined with dioxane precipitation method. The configuration and crystal parameters of All~ nitrate crystal was described and compared with water-soluble Al13 hydrochloride crystal with octahedral configu- ration synthesized by ethanol-dioxane precipital：ion method and Al13 sulfate crystal with tetrahedral configuration repor- ted in literature. The XRD spectra showed that the Al13 hydrochloride crystal and the AI~ nitrate crystal belong to monoclinic system and orthorhombic system, respectively. The difference of anion species would result in the differ- ence in crystal dimension, interplanar distance, crystal configuration, and solubility. The structure and properties of Al13 will be studied from the direction of anion.
