3-dionehydrazinecarboxamide (L1H) and 5-iodo-indol-2,3-dionehydrazinecarbothioamide (L2H) and their organotin(IV) complexes have been synthesized. The biologically potent ligands interacted with the Sn(IV) metal ion in 1:1 and 1:2 molar ratios, respectively, in dry methanol. Tentative structural conclusions of organotin(IV) complexes are described with the support of elemental analyses, melting points, and molecular
摘要 合成了新的席夫碱 5-iodo-indol-2,3-dionehydrazinecarboxamide (L1H) 和 5-iodo-indol-2,3-dionehydrazinecarbothioamide (L2H) 及其有机锡 (IV) 配合物。在无水甲醇中,具有生物活性的配体分别以 1:1 和 1:2 的摩尔比与 Sn(IV) 金属离子相互作用。在元素分析、熔点和分子量测定、红外、核磁共振(1H、13C 和 119Sn)和紫外-可见光光谱研究的支持下,描述了有机锡 (IV) 配合物的初步结构结论。光谱数据表明配体是一元双齿的,通过氮和硫/氧原子配位。因此,已经为 1:1 和 1:2 金属配合物提出了合适的三角双锥几何和八面体几何,分别。配体及其复合物已针对各种微生物进行了体外抗微生物活性的测试。所有复合物对两种细菌种类大肠杆菌和金黄色葡萄球菌均表现出良好的抗菌活性,并对两种
