| 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-的四个N原子和两个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. |
| Keywords: quinoline thiosemicarbazone complex crystal structure DNA-biding property. |
