%X A novel vanadium(IV) phosphate VIIIVIV3O3(PO4)3 has been synthesized and crystallized (1073 K,
sealed silica tube, a few milligrams of PtCl2 as mineralizer). According to the single-crystal structure
analysis [orthorhombic, F2dd (No. 63), Z = 24, a = 7.2596(8) Å, b = 21.786(2) Å, c = 38.904(4) Å
(lattice parameters from Guinier photographs), R1 = 0.032, wR2 = 0.067, κ-CCD diffractometer, 83 949
reflections measured, 6836 independent, 5986 with I > 2σ(I), 299 variables], VIIIVIV3O3(PO4)3 belongs
to the Lipscombite/Lazulite structure family. At 1073 K VIIIVIV3O3(PO4)3 is in thermodynamic equilibrium
with (VO)2P2O7, VO2, and VPO4. Substitution of V3+ in VIIIVIV3O3(PO4)3 by Cr3+ and Fe3+ is possible.
Like vanadylpyrophosphate the oxide phosphates MIIIVIV3O3(PO4)3 (MIII: V, Cr, Fe) show significant
catalytic activity in selective oxidation of n-butane and 1-butene to maleic acid anhydride.
