Abstract Complexes [Zn(L2)2Cl2], [Pd2(L2)2Cl4], and CuL2Cl, where L2 is (−)-camphor thiosemicarbazone, were synthesized. The structures of complexes [Zn(L2)2Cl2] and [Pd2(L2)2Cl4] were determined by X-ray diffraction. The crystal structure of complex [Zn(L2)2Cl2] contains mononuclear molecules with distorted tetrahedral ZnCl2S2} coordination units and monodentate L2 ligands. Complex [Pd2(L2)2Cl4]
摘要合成了配合物[Zn(L2)2Cl2],[Pd2(L2)2Cl4]和CuL2Cl,其中L2为(-)-樟脑硫代半乳糖胺。通过X射线衍射确定配合物[Zn(L2)2Cl2]和[Pd2(L2)2Cl4]的结构。配合物[Zn(L2)2Cl2]的晶体结构包含具有扭曲的四面体ZnCl2S2}配位单元和单齿L2配体的单核分子。配合物[Pd2(L2)2Cl4]具有双核结构,Pd金属中心通过L2-配体通过L2-S原子连接。根据IR和NMR光谱,络合物CuL2Cl在离子Cu +的配位域中包含S和Cl原子。还获得了配合物[Pd(tsc)Cl2]和Zn(tsc)2Cl2(其中tsc为硫代氨基脲),以确定萜烯部分对这些化合物的细胞毒性的影响。单核络合物[Pd(tsc)Cl2]包含NSCl2平面方配位多面体,tsc是二齿螯合配体。接下来研究tsc,L2以及与tsc和L2的复合物对MCF-7细胞系活力的影响。结果表明
