Heterocyclic compounds with different functional group have a chelating inheritance. It is also proved that the metal chelates have drugs activities and some metal chelates acts as plant growth promoter. Hence we have synthesized heterocyclic compound, 4-bromo-2-hydrazino-6-methyl benzothiazole and different experiments were conducted to see the chelating tendency of newly synthesized heterocyclic compound. When 4-bromo-2-hydrazino-6- methyl benzothiazole were treated with metal ions like Fe++, Co++, Ni++ at different PH and different laboratory conditions, the metal chelates are formed. The synthesized complexes were purified and characterized by analytical, thermal and spectral parameters.
