Neutral Ru(II)-arene complexes [Ru(η6‐p-cymene)(PAr3)Cl2], PAr3 where Ar = 3,5-((CH3)3C)2C6H3–, 3,5-(CH3)2C6H3–, 4-CH3O-3,5-(CH3)2C6H2– and 4-CH3O-C6H4– were synthetized and fully characterized including single-crystal X-ray diffraction. The ligands have empirical logPow = 10.29, 7.38, 7.08, 5.43 (vs. PPh3 = 5.14). They have sufficiently low solubility to form Langmuir monolayers on water in accordance
中性的Ru(II)配合物-arene的[Ru(η 6 - p -cymene)(PAR 3)氯2 ],PAR 3其中Ar = 3,5 - ((CH 3)3 C)2 C ^ 6 ħ 3 - , -合成了3,5-(CH 3)2 C 6 H 3 –,4-CH 3 O-3,5-(CH 3)2 C 6 H 2 –和4-CH 3 O-C 6 H 4 –并对其进行了充分表征包括单晶X射线衍射。配体具有经验logP流 = 10.29,7.38,7.08,5.43(VS。PPH 3 = 5.14)。它们具有足够低的溶解度以根据总分子大小在水上形成Langmuir单层。进行了密度泛函理论(DFT)计算,以确定分子和电子结构,并解释了伏安法和UV-Vis光谱学的结果。针对MRC-5(非肿瘤性肺),A549(肺癌)和MDA-MB-231(乳腺癌)细胞系进行了细胞毒性测定。Ar = 3,5-((CH 3)3 C)2
