Abstract: VPO polymer β-NH4(VO2)(HPO4) was synthesized from the mixture of NH4VO3 and NH4H2PO4 in aqueous acidic solution. This hydrogenphosphate vanadate crystallizes in the orthorhombic space group Pbca with a=0.68060(8) nm, b=0.92570(5) nm, c=1.77370(2) nm, V=1.1175(3) nm 3, Z=8, Dc=1.743 g·cm-3, μ=88.54 cm-1 and R=0.051. The structure is built up from VO5 square pyramid linked by trans-vertices through the bridged oxygen atom to form an one dimensional isolated chain of {VO2HPO4}nn- nunning along the a axis.
