| 摘要: 合成并通过单晶衍射、元素分析、红外光谱表征了配合物 [CoL2]Cl·2CH3OH (1)和[CdL2] (2)的结构(HL为喹啉-8-甲醛缩硫代氨基脲).单晶衍射结果表明,配合物1和2中金属离子采取相同的配位模式,分别与来自硫醇化脱质子的配体L-的4个N原子和2个S原子配位,采取扭曲的八面体配位构型.配合物1和2能够与DNA结合,结合模式分别为静电结合和部分插入. | |

| Abstract: Two complexes [CoL2]Cl·2CH3OH (1) and [CdL2] (2) (HL=(quinolin-8-ylmethylene)thiosemicarbazide) have been synthesized and structurally determined by single-crystal X-ray diffraction. The results show that the metal ion in each complex with a distorted octahedron geometry is surrounded by two anionic thiosemicarbazone ligand with N2S donor set. Complexes 1 and 2 can bind to DNA via electrostatic intercalation and partial intercalation modes, respectively. CCDC: 1436092, 1; 1436093, 2. | |
