were conducted primarily by spectroscopic techniques while the single crystal X-ray analysis revealed the distorted octahedrons of the respective metal compounds. Voltammetry experiments of 1–3 illustrated one-electron quasi-reversible redox waves which are attributed to metal oxidation state interconversions.

钌席夫碱金属配合物的抗癌活性与其空间因子和理化性质密切相关。我们研究的核心目标是合成和表征源自肉桂醛、孜然醛或 4-氨基安替比林的新型钌席夫碱化合物。此外,上述金属化合物和两种先前报道的钌席夫碱化合物的立体电子特征与其抗氧化和生物分子相互作用能力有关。因此,我们证明了具有螯合 N-供体配体的新型单核钌 (III) 化合物的形成:fac -[RuCl 3 (PPh 3 )(ap)] ( 1 ) (ap = 4-氨基安替比林),反式-P-[Ru(PPh 3 ) 2 (cinap) 2 ](PF 6 ) ( 2 ) (cinap = 1,5-二甲基-2-苯基-4-[3-苯基丙-2-en-1-亚基]氨基} -1,2-二氢-3- ħ吡唑-3-酮)和顺式-氯,反式- P-将[RuCl 2(PPH 3)2(cumbh)](3)(cumbh = N” - (4-异丙基亚苄基)苯甲酰肼)。结构确认主要通过光谱技术进行,而单晶
