摘要
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 \[Al2（PO4）2（H2O）2F2\]2- 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.
