AbstractUranium(VI) peroxo complexes of composition [UO(O2)L–L(NO3)2], where L–L are the Mannich base ligands morpholinobenzyl urea, piperidinobenzyl urea, morpholinobenzyl thiourea, piperidinobenzyl thiourea, morpholinomethyl thiourea, piperidinomethyl thiourea, or morpholinomethyl urea, are reported. The synthesized complexes were characterized by use of a variety of physicochemical techniques, viz
摘要组成为[UO(O 2)L–L(NO 3)2 ]的铀(VI)过氧配合物,其中L–L为曼尼希碱配体吗啉代苄基尿素,哌啶子基苄基脲,吗啉代苄基硫脲,哌啶子基苄基硫脲,吗啉代甲基硫脲,哌啶子基甲基硫脲报道了吗啉代甲基脲。通过使用多种物理化学技术来表征合成的复合物。元素分析,摩尔电导率,磁化率测量,红外,电子,质量,1 H NMR和13C NMR光谱和TGA / DTA研究。这些研究表明,该配合物本质上既是非电解的又是抗磁性的。配体通过羰基氧或硫代羰基硫和环氮以二齿模式与金属结合。质谱证实了配合物的分子量。该复合物的抗真菌活性大于相应的游离配体的抗真菌活性。 图形概要
