以2-甲基喹 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 coordination compounds of 2-methylquinoxaline with Cu(ClO4)2 or Cu(BF4)2 have been synthesized and characterized by elemental anal., elec. conductivity, IR, ESR and electronic spectra, TGA and temperature dependent (1.5-300 K) magnetic susceptibility measurements. The composition and configuration of these complexes have been proposed. A linear Cu(II)-O-Cu(II) bridged structure existed in 3 of the antiferromagnetic dimeric complexes.
