Al13nitrate crystal,whose configuration was similar with cuboid,was synthesized by SO2-4/Pb2+precipitation-exchange method combined with dioxane precipitation method.The configuration and crystal parameters of Al13nitrate crystal was described and compared with water-soluble Al13hydrochloride crystal with octahedral configuration synthesized by ethanol-dioxane precipitation method and Al13sulfate crystal with tetrahedral configuration reported in literature.The XRD spectra showed that the Al13hydrochloride crystal and the Al13nitrate crystal belong to monoclinic system and orthorhombic system,respectively.The difference of anion species would result in the difference in crystal dimension,interplanar distance,crystal configuration,and solubility.The structure and properties of Al13will be studied from the direction of anion.
