-nonyl, ptpy = 2-( p -tolyl)pyridinato). All compounds were characterized by elemental analyses, mass spectra and 1 H and 13 C NMR spectra. The compounds 1, 6, 7, 8, 10 were also examined by X-ray crystallography and their proposed octahedral tris-chelate structure with trans configuration of the cyclometalating tolylpyridinato N atoms was proven. All compounds display significant cytotoxicity against
摘要二聚环金属化配合物[M(µ-Cl)(ptpy)2} 2]与对称的二烷基取代的联吡啶反应,然后与KPF 6复分解生成配合物盐[M(ptpy)2(6,6 ''-二甲基-联吡啶)] PF 6和[M(ptpy)2(4,4'-二烷基-联吡啶)] PF 6,(M = Rh,Ir;烷基=甲基,n-丙基,叔丁基或n -壬基,ptpy = 2-(对甲苯基)吡啶基)。所有化合物均通过元素分析,质谱,1 H和13 C NMR光谱进行表征。还通过X射线晶体学检查了化合物1、6、7、8、10,并且证明了它们提出的具有环金属化甲苯基吡啶并成N原子的反式构型的八面体三螯合物结构。所有化合物对人癌细胞系MCF-7和HT-29均显示出显着的细胞毒性。
