| 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[(Cu)(L)(Cl)2](1),[(Zn)(L)(Cl)2](2)和{[(Cd)2(L)(I)4]}n（3）的结构(L为2-吡啶肼啶缩2-乙酰吡啶)。单晶衍射结果表明,配合物1和2同构,中心金属分别与来自配体的NNN电子供体以及2个氯离子配位形成一个扭曲的三角双锥结构。在配合物3中,相邻的2个五配位的Cd(Ⅱ)离子通过2个μ2-I-阴离子桥连形成沿c轴方向的一维链。此外还研究了配合物1~3的荧光及热性质。 |

| Abstract: Three complexes [(Cu)(L)(Cl)2](1), [(Zn)(L)(Cl)2](2) and {[(Cd)2(L)(I)4]}n(3) (L is derived from 2-acetyl pyridine and picolinamide hydrazone) have been synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. X-ray diffraction analysis results show that complexes 1 and 2 are isostructural. The coordination geometry of the metal ion in each complex is a distorted trigonal biyramid with three nitrogen atoms from the ligand L and two chloride anions. However, in complex 3, two adjacent five-coordinated Cd(Ⅱ) ion are connected by two bridged μ2-I- anions, resulting in the formation of one-dimensional chain along c axis. In addition, the thermal stability and luminescent properties of the complexes are also studied in detail. |
