The inorganic-organic hybrid [VIV4O 10VV2O4] (C6H 14N2)•H2O polymeric framework was prepared under mild hydrothermal conditions from a mixture of DABCO and V 2O5 in deionized water with a 1:1:450 mole ratio, at neutral pH. The reaction was carried out at 180°C for 3 days under autogenous pressure yielding phase pure crystals product. The crystal structure was studied using both powder and single crystal X-ray crystallography, revealing the structure to be of the ({UuDd}:T*)α′ type in the SP+T class and Z-T subclass. The presence of the organic cation was confirmed by FT-IR spectrum and chemical composition analysis. The structure was thermally stable up to over 400°C, and showed ferromagnetic character at room temperature with the maximum molar susceptibility of 8.26 × 10 -3 emu/mol-1 at zero applied field. © 2006 Springer Science+Business Media, LLC.
