Abstract
The first example of an aluminophosphate containing organic anions covalent ly bonded to the framework of the structure is reported; [NH3CH2CH2NH3](2.5 )[Al4H(HPO4)(4)(H2PO4)(2)(C2O4)(4)] was prepared hydrothermally and adopts a layered structure. The oxalate groups act as bidentate ligands to Al3+ an d hold the structure together by strong interlayer P-O-H-oxalate hydrogen b onds. The structure was solved from synchrotron X-ray diffraction data coll ected on a very small single crystal, space group C2/m, a = 19.683(4) Angst rom, b = 12.360(3) Angstrom, c = 16.734(3) Angstrom, beta = 110.51(3)degree s.
