Abstract
A new layered fluoroaluminophosphate [C4H12N2][Al2 (PO4)2(H2O)2 F2] (compound I) was synthesized hydrothermally. It crystallizes in the monoclinic space group P21/c with a=1.10240(7) nm, b=0.69551(4) nm, c=0.92805(5) nm, β=111.027(3)°, Z=6, R1=0.0379, wR2=0.0792 (all data). Its structure contains [Al2(PO4)2 (H2O)2 F2]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 [100] direction. The sheets are held together by diprotonated piperazine cations decomposed from 1-methylpiperazine through extensive hydrogen bonds.
