Abstract

Two dinuclear complexes [M2(EGTB)(NO3)2(DMF)2](NO3)2 · 2DMF (M = Cu, 1; Co, 2) were synthesized and structurally characterized, EGTB is N,N,N',N'-tetrakis (2-benzimidazolylmethyl)-1,4-diethylene amino glycol ether, and DMF is dimethylformamide. The polyphenol oxidase (PPO) activities of 1 and 2 on pyrogallol oxidation have been investigated, showing that the rate constants kcat increase with increases of reaction temperatures and pH.
