以2-甲基喹噁啉为配体合成了五种含有阴离子ClO_4~-或BF_4~-的铜(Ⅱ)配合物,利用元素分析、红外光谱、电子光谱、电导、热重谱、ESR谱及变温磁化率的测定推测了配合物的结构,提出双核铜配合物中含有直线型单氧桥Cu(Ⅱ)-O-Cu(Ⅱ)键的可能构型。
Five kinds of Cu (Ⅱ) complexes containing anions of ClO 4 - or BF 4 - were synthesized by using 2-methylquinoxaline as ligand. Elemental analysis, IR, EDS, TG, ESR spectra And the determination of the temperature-dependent magnetic susceptibility. The possible structure of Cu (Ⅱ) -O-Cu (Ⅱ) bond in the dinuclear copper complex is proposed.
