摘　　要：Using n-propylamine as a template,deioned water and secondary-butanol(butan-2-ol)as solvents,a three-dimensional(3D)open-framework aluminophosphate[C3NH10]·[HAl3P3O13](1)and a two-dimensional layered aluminophosphate[C3NH10]3·[Al3P4O16](2)were crystallized from the initial mixtures with compositions of Al2O3:2.4 P2O5:5.0 n-propylamine:100 H2O/butan-2-ol,respectively.They are characterized by X-ray powder diffraction(XRD),thermogravimetric(TG),and elemental(CHN)analyses and structurally determined by single-crystal X-ray diffraction analysis.Compound 1 crystallizes in the monoclinic space group P21/c with a=0.85831(13)nm,b=1.7677(3)nm,c=1.04353(12)nm,=123.887(9)°,and V=1.3143(3)nm3.Compound 2 crystallizes in the monoclinic space group P21/c with a=1.1313(2)nm,b=1.4874(3)nm,c=1.8020(6)nm,=125.07(2)°,and V=2.4817(11)nm3.The results show that the properties of solvent have a significant influence on the structure-directing effect of n-propylamine in the crystallization of the open-framework aluminophosphates.Using n-propylamine as a template,deioned water and secondary-butanol（butan-2-ol）as solvents,a three-dimensional（3D）open-framework aluminophosphate[C3NH10]·[HAl3P3O13]（1）and a two-dimensional layered aluminophosphate[C3NH10]3·[Al3P4O16]（2）were crystallized from the initial mixtures with compositions of Al2O3：2.4 P2O5：5.0 n-propylamine：100 H2O/butan-2-ol,respectively.They are characterized by X-ray powder diffraction（XRD）,thermogravimetric（TG）,and elemental（CHN）analyses and structurally determined by single-crystal X-ray diffraction analysis.Compound 1 crystallizes in the monoclinic space group P21/c with a=0.85831（13）nm,b=1.7677（3）nm,c=1.04353（12）nm,=123.887（9）°,and V=1.3143（3）nm3.Compound 2 crystallizes in the monoclinic space group P21/c with a=1.1313（2）nm,b=1.4874（3）nm,c=1.8020（6）nm,=125.07（2）°,and V=2.4817（11）nm3.The results show that the properties of solvent have a significant influence on the structure-directing effect of n-propylamine in the crystallization of the open-framework aluminophosphates.
