以三(3,5-二甲基吡唑甲基)胺(TMPzA)及2,5-噻吩二羧酸为配体合成了2个双核Cu的配合物[Cu_2(DMPzA)_2(TPDC)_2]ClO_4(1)和[Cu_2(TMPzA)_2(TPDC)(H_2O)_2](ClO_4)_2(2)。在1中,配体TMPzA发生裂解,以二(3,5-二甲基吡唑甲基)胺(DMPzA)与Cu配位,并在2个Cu原子之间形成一个大环,2个Cu原子之间的距离为0.786 84 nm。清除自由基实验发现,配合物1比2具有较好的清除自由基活性。
Two binuclear Cu complexes [Cu_2 (DMPzA) _2 (TPDC) _2] have been synthesized from tris (3,5-dimethylpyrazolylmethyl) amine (TMPzA) and 2,5-thiophene dicarboxylic acid ] ClO_4 (1) and [Cu_2 (TMPzA) _2 (TPDC) (H_2O) _2] (ClO_4) _2 (2). In 1, the ligand TMPzA was cleaved and coordinated with Cu with di (3,5-dimethylpyrazolylmethyl) amine (DMPzA) and formed a macrocycle between two Cu atoms, two Cu The distance between atoms is 0.786 84 nm. Free radical scavenging experiments found that complexes 1 to 2 have better free radical scavenging activity.
