dihydro-3H-pyrazol-3-one, C18H17N3O2 with zinc ions to form a new coordination compound with chemical formula C36H36N6O4Zn. This is the first effort to determine the vibrational properties of the C36H36N6O4Zn using infrared and Raman spectroscopy combined with Density functional based methods (DFT). The vibrational modes analyses were performed based on Potential Energy Distribution (PED). A comparison of
摘要 在这项研究中,我们协调了席夫碱 4-[(1E)-(2-Hydroxyphenyl)methylidene]amino}-1,5-dimethyl-2-phenyl-1,2 dihydro-3H-pyrazol-3-one ,C18H17N3O2与锌离子形成新的配位化合物,化学式为C36H36N6O4Zn。这是首次使用红外和拉曼光谱结合基于密度泛函的方法 (DFT) 来确定 C36H36N6O4Zn 的振动特性。基于势能分布 (PED) 进行振动模式分析。理论和实验光谱的比较使我们能够分配晶体的大多数正常模式并解释实验结果。根据我们的结果,锌离子与两个亚胺氮和两个吡唑啉酮氧配位。
