Vanadyl hydrogenphosphate sesquihydrate VOHPO P 1.5H O was prepared by reduction of VOPO P 2H O suspended 4 2 4 2 ลฝ . in refluxed 1-butanol and activated at 4808C over 10 h on-stream to give VO P O , which revealed high specific activity 2 2 7 ลฝ . per unit surface area in the vapor-phase oxidation
The crystal structure of the quantum-spin chain compound (VO) 2 P 2 O 7 was studied by electron, X-ray, and neutron di4raction. A polycrystalline sample which clearly exhibited a singlet ground state in magnetic susceptibility measurements was examined. Electron di4raction experiments revealed syste
