| Abstract: | The title compounds: VOC_4H_4O_4, VOC_4H_4O_5, (NH_4)_2VO(C_4H_4O_5)_2, VO(C_3H_5O_3)_2 and VOC_6H_8O_4 were synthesized and their composition and structure were ascertained by elemental, magnetic susceptibility and IR analyses. Investigations by TG, DTA and X-ray powder diffraction showed that the thermal decomposition property of these complexes were highly dependent on their structure. It was found that the VOC_6H_8O_4 was the best one to prepare vandium carbide V_4C_3, by heating it at 420 C in an inert atmosphere. |
