The copper(II) complex [Cu(NO3)(PyTz)2](NO3) has been previously characterized means X-ray powder diffraction and now studied by IR spectroscopy, UV-Vis-NIR diffuse reflectance, magnetic susceptibility measurement, electronic spin resonance (ESR) and thermal analysis. The results are correlated with a distorted square pyramidal coordination around copper(II) ion rather than the cis-distorted octahedral
铜 (II) 配合物 [Cu(NO3)(PyTz)2](NO3) 先前已通过 X 射线粉末衍射进行表征,现在通过 IR 光谱、UV-Vis-NIR 漫反射、磁化率测量、电子自旋进行了研究共振(ESR)和热分析。结果与铜(II)离子周围的扭曲方形锥体配位相关,而不是与其结构良好一致的CuN4OO'发色团的顺式扭曲八面体立体化学。同样,为了指示配合物向哪种方锥体异构体扭曲,Carugo 和 Bisi 提出的方法已应用于 [Cu(NO3)(PyTz)2](NO3) 的结构数据。推导出三角双锥几何存在较大畸变,接近四棱锥几何,
