phenylazopyridine (AZPY) complexes have been synthesised and characterised; [Os(η6-arene)(5-RO-AZPY)X] Y, where arene = p-cym or bip, AZPY is functionalized with an alkoxyl (O-R, R = Me, Et, nPr, iPr, nBu) or glycolic (O-CH2CH2O}nR*, n = 1–4, R* = H, Me, or Et) substituent on the pyridyl ring para to the azo-bond, X is a monodentate halido ligand (Cl, Br or I), and Y is a counter-anion (PF6−, CF3SO3− or
已经合成和表征了二十四种新型有机金属lic(II)苯基偶氮吡啶(AZPY)配合物。[OS(η 6 -arene)(5-RO-的Azpy)X] Y,其中芳烃= p -cym或BIP,的Azpy与烷氧基官能化(OR,R =甲基,乙基,Ñ PR,我PR,Ñ BU)或乙醇酸(O- CH 2 CH 2 ö} ñ R *,N = 1-4,R * = H,Me中,或Et上的吡啶环)的取代基对位到偶氮键,X是单齿halido配体(Cl,Br或I),和Y为抗衡阴离子(PF 6 -,CF 3 SO 3 -或IO 3 -)。两个配合物的X射线晶体结构证实了它们的“半三明治”结构。水溶性取决于X,AZPY取代基,芳烃和Y。碘配体在水中高度稳定(X = I⋙Br> Cl),并且对A2780(卵巢),MCF-7(乳腺癌)表现出最高的抗增殖活性,SUNE1(鼻咽)和OE19(食道)癌细胞,其中一些获得纳摩尔效价和良
