polymeric dioxouranium(VI) of azosulphadrugs [(azodrug substances) azobenzene sulphonamides] were prepared for the first time. The infrared spectra of the samples were recorded and their fundamental vibration wave number was obtained. The resulting polymeric uranyl complexes were characterized on the basis of their elemental analyses, conductance and spectral (IR, NMR, and electronic spectra) data. The ligation
首次制备了五种新型的双核聚合物二氧杂鎓(VI)的偶氮磺胺药物([偶氮药物物质]偶氮苯磺酰胺)。记录样品的红外光谱并获得其基本振动波数。根据其元素分析,电导率和光谱(IR,NMR和电子光谱)数据对所得的聚合物铀酰复合物进行表征。偶氮磺胺类药物配体与铀酰(II)离子的连接模式已得到严格分配,并根据其IR和铀酰(II)配合物进行了正确处理。理论方面是根据众所周知的5d–4f跃迁理论进行描述的。配位几何和电子结构是从用于新型聚合物配合物建模的框架中确定的。的值ν 3含有UO所制备的复合物的2 2+被成功地用于计算力常数,˚F UO(1N 10 -8 N / A)和键长[R UO的UO键。使用Wilson方法,矩阵方法,Badger公式以及Jones和El-Sonbati方程从拉伸和相互作用力常数的值计算U–O键距。根据“ Badger规则”,“ Jones”和“ El-Sonbati方程”令人满
