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.
