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. CCDC: 1411232, 1; 1411233, 2.
