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. 相似文献

Hydrothermal synthetic parameters were studied and optimized for the preparation of new coordination polymeric materials based
on Co(II) and 4,4′-bipy. A new polymeric compound, [Co2(H2O)2(OH)2(4,4′-bipy)8](NO3)2·2(4,4′-bipy) 10(H2O) (1), was prepared and structurally characterized by single crystal experiment. The framework of (1) is made up of two different one-dimensional substructures, i.e., the neutral chain A and positively charged chain B, both of which share the same nodes and node linkers. This is rarely found, especially from a one-pot crystal growth technique.
Two other crystals were also identified, i.e., [Co(SO4)(H2O)3(4,4′-bipy)]·2(H2O), and K2Co(H2O)6(SO4)2. The optimization of synthetic parameters apparently favors the formation of different polymeric structures, and this can
be experimentally fine tuned. The influences of these parameters on phase formation, purity and crystal growth are discussed.
The complicated thermogravimetric property of the new compound is also reported. 相似文献
