New oscillating reactions catalyzed by a bistetraazacrocyclic nickel (Ⅱ) complex Ni2L(ClO4), where L is bis(11,13 dimethyl 1,4,7,10 tetraza 10,13 cyclotridecadien 12 ylidene), in acidic bromate medium have been studied. We obtained the concentration ranges of main reactant within which the oscillations were observed in the system. We discussed the influence of temperature, Vc ,Br-, Ag+, Hg2+, acetonitrile or acrylamide on the oscillations. The results indicated that Br-played an important role in the control reaction progress and free radical might be involved in the reaction process. We recorded the oscillation trajectories of this system. It was different from classical BZ reaction and some other tetraazamacrocyclic complexes catalyzed system.
