| 摘要: 合成并通过单晶衍射表征了配合物[Cd(L)(H2O)(NO3)2](1)和[Cd(L)I2]·CH3OH(2)(L=喹啉-8-甲醛对羟基苯甲酰腙)。单晶衍射结果表明,在配合物1中,Cd(Ⅱ)分别与1个三齿配位的酰腙配体,1个水分子,1个单齿配位和1个双齿配位的硝酸根配位,从而拥有单帽三棱柱配位构型。然而,配合物2中,Cd(Ⅱ)离子采取扭曲的四方锥配位构型,与来自配体L的N2O电子供体以及2个碘离子配位。此外还详细研究了配合物1和2的热稳定性及荧光性质。 |

| Abstract: Two complexes [Cd(L)(H2O)(NO3)2] (1) and [Cd(L)I2]·CH3OH (2) (L=4-hydroxy-N-((quinolin-8-yl)methylene)benzohydrazide) have been synthesized and structurally determined by single-crystal X-ray diffraction. The results show that the Cd(Ⅱ) ion in 1 with a mono-capped trigonal prismatic geometry is surrounded by one acylhydrazone ligand with N2O donor set, one water molecule, one mono-dendate and one bidendate nitrate anions. However, the coordination geometry of the Cd(Ⅱ) ion in 1 is a distorted tetragonal pyramid with oxygen and two nitrogen atoms provided by the ligand L and two iodide anions. The thermal stabilities and luminescent properties of both complexes are also investigated in detail. |
