Summary
The inorganic–organic hybrid [VIV 4O10VV 2O4] (C6H14N2)·H2O polymeric framework was prepared under mild hydrothermal conditions from a mixture of DABCO and V2O5 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.
