| 摘 要： | 自从1982年Wilson等发现一类新型微孔材料磷酸铝分子筛(AlPO4-n)以来，大量具有新颖结构的磷酸铝化合物被合成出来，它们在催化、离子交换、吸附和主-客体组装等方面均具有潜在的应用前景，这类化合物大多是在水热或溶剂热体系中和有机模板剂存在条件下合成的，1978年，Flanigen等首先在反应体系中加入氟离子作矿化剂合成了硅晶体，后来，氟离子方法在硅铝体系和金属磷酸盐体系中也得到了广泛的应用，氟离子在反应过程中起到矿化剂或结构导向剂的作用，

| Abstract: | A new layered fluoroaluminophosphate Al2(PO4)2(H2O)2F2(compound Ⅰ) was synthesized hydrothermally. It crystallizes in the monoclinic space group P21/c with a=1.102 40(7) nm, (b=0.695 51(4) nm,) c=0.928 05(5) nm, β=111.027(3)°, Z=6, R1=0.037 9, wR2=0.079 2(all data). Its structure contains Al2(PO4)2(H2O)2F22- macroanonic sheets built up from PO3(O) tetrahedra and AlO3F2(H2O) octahedra to form three-, four-, six-membered ring-net stacked sheets in an AAAA sequence along direction. The sheets are held together by diprotonated piperazine cations decomposed from 1-methylpiperazine through extensive hydrogen bonds. |
