Thermal stability of some azo-derivatives and their complexes - 1-(2-benzothiazolyl)-3-methyl-4-azo-pyrazil-5-one derivatives and their Cu(II) complexes

This paper deals with the first investigation concerning the thermal stability of two 1-(2-benzothiazolyl)-3-methyl-4-azo-pyrazil-5-one derivatives and their Cu(II) coordination compounds of type ((C(4)H(9))(4)N)(2)[Cu(L)(2)]. The thermal decomposition steps were established.
