| 中文摘要: |
| 合成了一种用作前驱体的、中性、具有冠状结构的新型水溶性四核钯配合物十一水.醋酸亚胺合钯([CH3COO)4Pd4(NH2)4].11H2O)，用元素分析和X射线单晶衍射仪(XRD)对其结构进行了表征，用热重-差热(TG-TDA)测试其热分解特性。结果表明，该化合物为正交晶系、Pccn空间群，其晶体它的结构是以4个(CH3COO)Pd片段分别和4个-NH2配体桥接，形成八原子的环状四核钯的配合物，也获得了该配合物的键长和键角等参数。TG-DTA测试显示化合物分解峰出现在231.4℃ (低分解温度)，该配合物中不含氯、膦和硝酸根，可作为新型的钯前驱体。 |
| 英文摘要: |
| [CH3COO)4Pd4(NH2)4].11H2O, a new water-soluble and neutral type tetra-palladium(Ⅱ) cyclic complex was synthesized and characterized by element analysis and single crystal X-ray diffraction (XRD). Its thermal decomposition characteristics were characterized by TG-TDG. Its crystal belongs to orthorhombic space group Pccn. The crystal data shows that four (CH3COO)Pd fragments bridged with -NH2 ligand. The bond length and angle was obtained from its XRD pattern. TG-TDA results showed that the peak decomposition temperature was 231.4℃ (Low decomposition temperature). The complex doesn’t contain chlorine, phosphine and nitrate with good water-solubility, and it can be used as palladium precursor. |
