Abstract New solid metal complexes of nicotinic hydrazides with strong biological activity have been prepared in neutral and alkaline media having 1:1 and 1:2 metal/ligand ratios. The materials obtained were subjected to careful programs of elemental analysis, quantitative thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Interesting results were obtained in agreement with each
摘要 在金属/配体比为 1:1 和 1:2 的中性和碱性介质中制备了具有强生物活性的新型烟碱酰肼固体金属配合物。对获得的材料进行元素分析、定量热重分析 (TGA) 和差热分析 (DTA) 的仔细程序。有趣的结果相互一致,导致更好地了解固体配合物的确切分子式及其与制备方式、沉淀介质和有机配体分子中的各种取代相关的热稳定性。最后,M/L 比为 1:2 的金属螯合物似乎具有较低的热稳定性。
