| 摘要: 合成并通过X射线单晶衍射、元素分析及红外光谱表征了配合物[Ni(L)2] (1)和[Cd(HL)(CH3OH)(NO3)2] (2)的结构(HL为2-乙酰吡嗪缩肼基甲酸甲酯)。单晶衍射结果表明,配合物1中,Ni(Ⅱ)离子与来自2个阴离子配体L-的N2O电子供体配位,形成扭曲的八面体配位构型。在配合物2中,Cd(Ⅱ)离子拥有双帽三棱柱配位构型,与1个中性配体HL,2个双齿配位硝酸根和1分子甲醇配位。此外还研究了配合物1和2的荧光及热性质。 | |

| Abstract: Two complexes, namely [Ni(L)2] (1) and [Cd(HL)(CH3OH)(NO3)2] (2) (HL is derived from 2-acetyl pyrazine and methyl hydrazinocarboxylate) have been synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. X-ray diffraction analysis results show that the central Ni(Ⅱ) ion in complex 1 is surrounded by two independent anionic ligands with N2O donor set, thus possesses a distorted octahedral coordination geometry. However, in complex 2, the Cd(Ⅱ) ion with bicapped-triangular prism geometry is coordinated with one neutral ligand HL, two bidentate nitrate anions and one methanol molecule. In addition, the thermal stability and luminescent properties of the complexes are also studied in detail. | |
