Using n-propylamine as a template,deioned water and secondary-butanol(butan-2-ol)as solvents,a three-dimensional(3D)open-framework aluminophosphate[C_(3)NH_(10)]·[HA_(13)P_(3)O_(13)](1)and a two-dimensional layered aluminophosphate[C_(3)NH_(10)]_(3)·[A_(13)P_(4)O_(16)](2)were crystallized from the initial mixtures with compositions of Al_(2)O_(3):2.4 P_(2)O_(5):5.0 n-propylamine:100 H_(2)O/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 P2_(1)/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 P2_(1)/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)nm^(3).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.
