| 摘要: 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[Cu2（DMPzA）2（TPDC）2]ClO4 （1）和 [Cu2（TMPzA）2（TPDC）（H2O）2]（ClO4）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。 |

| Abstract: By using a tripodal ligand tris(3,5-bimethyl-pyrazolylmethyl)amine (TMPzA) and a bridged ligand thiophenedicarboxylic acid (H2TPDC), two binuclear copper(Ⅱ) complexes have been synthesized and characterized. It has been found that TMPzA lost an arm and coordinated to copper with di(3,5-bimethyl-pyrazolylmethyl)amine(DMPzA) in complex [Cu2(DMPzA)2(TPDC)2]ClO4 (1). The structure presented a microcycle with the Cu(1)…Cu(1A) distance of 0.786 84 nm. The complex [Cu2(TMPzA)2(TPDC)(H2O)2](ClO4)2 (2) is a binuclear structure and with the TMPzA completely. The investigation in Feton system shows that complex 1 has better hydroxyl radicals scavenging property than that of complex 2. |
