  A new vanadium(III) phosphate, (NH4)[V(PO4)F], has been synthesized by using mild hydrothermal conditions under autogeneous pressure. The crystal structure has been solved from X-ray single crystal data. The compound crystallizes in the Pnna orthorhombic space group, with the unit-cell parameters a = 12.982(2), b = 10.608(1), c = 6.4789(6) Angstrom and Z = 8. The final R factors were R-1 = 0.077 [all data] and wR(2) = 0.068. The crystal structure consists of a three-dimensional framework formed by VO4F2 octahedra and tetrahedral (PO4)(3-) phosphate anions. The vanadium(III) cations from the VO4F2 octahedra are linked through the fluorine atoms giving rise to zig-zag chains. The ammonium cations are located in the cavities of the structure compensating the anionic charge of the [V(PO4)F](-) inorganic skeleton. The IR spectrum shows the characteristic bands of the phosphate anion. The diffuse reflectance spectroscopy allowed us to calculate the Dq and Racah parameters. The values are Dq = 1540, B = 505 and C = 2460 cm(-1). Magnetic measurements indicate the existence of weak ferromagnetic interactions. (C) 2003 Elsevier Science (USA). All rights reserved.
