A new bromido-coordinated mononuclear copper(II) complex [Cu(HL1)Br2] (1), and a new mononuclear copper(II) complex [CuL2(HL2)]ClO4·0.5H2O (2), with the hydrazone ligands 4-tert-butyl-N'-(1-(pyridin-2-yl)ethylidene)benzohydrazide (HL1) and 4-bromo-N'-(pyridin-2-ylmethylene)benzohydrazide (HL2), have been synthesized and structurally characterized by physico-chemical methods and single crystal X-ray determination. X-ray analysis indicates that the Cu atom in complex 1 is in distorted square pyramidal coordination, and that in complex 2 is in octahedral coordination. The catalytic property for epoxidation of styrene by the complexes was evaluated.
合成了一种新的溴配位单核铜（II）配合物[Cu(HL1)Br2]（1）和一种新的单核铜（II）配合物[CuL2(HL2)]ClO4·0.5H2O（2），其腙配体分别为4-叔丁基-N'-(1-(吡啶-2-基)亚乙基)苯甲酰肼（HL1）和4-溴-N'-(吡啶-2-基亚甲基)苯甲酰肼（HL2），并通过物理化学方法和单晶X射线测定对其进行了结构表征。X射线分析表明，配合物1中的铜原子处于扭曲的四方锥配位，配合物2中的铜原子处于八面体配位。评估了这些配合物对苯乙烯环氧化的催化性能。
