Al-3(PO4)(3)F-2, N2C4H14 is obtained by hydrothermal synthesis using 1
,4-diaminobutane as a template. Its structure is related to the ULM-3
type fluorometallophosphates: it is built up from corner-linked [Al-3(
PO4)(3)F-2] units composed of three (PO4) tetrahedra, two (AIO(4)F) tr
igonal bipyramids and one (AlO4F2) octahedron. The subnetwork of the 1
,4-diammoniumbutane cations induces a non-centric symmetry. Crystal da
ta: orthorhombic, space group Pbc2(1), a = 10.023(2) Angstrom, b = 18.
