copper(II) complex, isothiocyanato2-[2-(dimethylamino)ethylthio]ethanolato}copper(II), (Cu(CH3-nso)NCS), was prepared and characterized by elemental analysis, infrared and electronic spectra, magnetic susceptibility (90–300 K), and single-crystal X-ray diffraction. The complex exhibits a band at 25×103 cm−1 characteristic of alkoxo-bridged structure. The temperature dependence of the magnetic susceptibility
制备了双核铜(II)配合物,异硫氰酸根合2-[2-(二甲氨基)乙硫基]乙醇合}铜(II),(Cu(CH3-nso)NCS),并通过元素分析、红外和电子光谱表征,磁化率 (90–300 K) 和单晶 X 射线衍射。该配合物在 25×103 cm-1 处显示出具有烷氧基桥接结构特征的带。磁化率的温度依赖性是不寻常的,并且在 240-180 K 的温度范围内显示出巨大的变化。磁数据分别在两个温度范围内拟合到 Bleaney-Browers 方程(-2J=535 cm-1,对于 300 ≥T≥240 K;对于 170≥T≥90 K,−2J=595 cm−1)。
