    • A 10 mg of the sample of 1 was taken in a 70 μl alumina pan and heated from 25 to 500°C at a rate of 5°C/min in nitrogen atmosphere with a flow rate of 60-90 ml/min. A 10.02 mg sample of 2 was taken in a 70 μl alumina pan and heated in a nitrogen atmosphere from 25 to 500°C under a flow rate of 60-90 ml/min.

    • 2O (1.87 mmol) was added with continuous stirring. The resulting red solution was treated with an aqueous solution (1.8 ml) of 4-aminopyridine (3.4 mmol) to give a reddish black color solution. After refluxing this solution for 48 h it was allowed to stay at room temperature for two days. The dark red crystals were filtered from the orange mother liquor, thoroughly washed with hot water, and dried in air at room temperature to yield ∼118 mg (∼64.48% based on vanadium) of 1.

    • 2O (1.87 mmol) was added with continuous stirring to give a light green solution. The green solution was treated with an aqueous solution (1.8 ml) of 4-aminopyridine (3.4 mmol), which resulted into the formation of a green precipitate. The reaction mixture was transferred to a 23 ml Teflon-lined Parr autoclave and heated at 145°C for 4 days. The autoclave was then slowly cooled to room temperature for one day. The light green crystals, which were mixed with yellowish green and orange impurities, were filtered from the light green mother liquor and dried in air at room temperature. The light green crystals of 2 were separated from the impurity to yield ∼69.9 mg (∼38.23% based on vanadium) of pure material.
