For the purpose of improving the reactivity, metal- azole complexes were synthesized and their properties were investigated. 1H - Tetrazole and 1H - 1,2,4 - triazole were used for the lingands which contain nitrogen atoms and can coordinate to metals. Copper was selected as the central metal in anticipation of the catalytic effect. For the counter anion, nitrate was used. The 1H - tetrazole complex was obtained as the salt, [Cu(CHN4)2]H20. The 1H - 1,2,4 - triazole was obtained as [Cu(C2H3N3)2](NO3)2.
From the results of the sensitivity tests, the complexes were insensitive to impact and friction. However, they are sensitive to static eletctricity. Compared with pure azoles, the coordination changed the thermal stability and reactivity during the DSC meassurement. The complexes generated oxidative gases during the flash pyrolysis / FT - IR measurement while pure azole generated HCN. NH3 and hydrocarbons. From the deflagration test, it was found that these complexes could produce a large amount of gaseous species and the rate of pressure generation was high.
