New methods for the electrochemical synthesis of copper(II) and zinc(II) coordination compounds with pyridinecarboxylic acids (nicotinic and picolinic) have been developed. The resulting compounds were characterized by quantitative analysis and IR spectroscopy. The vibrational frequencies of the synthesized compounds were calculated by a DFT quantum-chemical method, and the experimental IR spectra
已经开发了用吡啶羧酸(烟碱和吡啶甲酸)电化学合成铜 (II) 和锌 (II) 配位化合物的新方法。所得化合物通过定量分析和红外光谱进行表征。通过DFT量子化学方法计算合成化合物的振动频率,并在此基础上解释实验红外光谱。发现吡啶羧酸根离子在所有情况下都在氮原子和羧酸根基团上配位,然而,在烟酸的情况下,这导致形成配位聚合物,而对于吡啶甲酸,形成单核配合物是典型的。
