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, deionized water and secondary-butanol (butan-2-ol) as solvents, a three-dimensional (3D) open-framework aluminophosphate [C3NH10] · [HAl3P3O13] layered aluminophosphate [C3NH10] 3. [Al3P4O16] (2) were crystallized from the initial mixtures with Al2O3: 2.4 P2O5: 5.0 n-propylamine: 100 H2O / butan-2-ol, powder diffraction (XRD), thermogravimetric (TG), and elemental (CHN) analyzes 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) and 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 and b = 1.4874 (3) nm, c = 1.8020 (6) nm, = 125.07 (2) °, and V = 2.4817 (11) nm3. These 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-fram ework aluminophosphates.
