基于3-乙基-2-乙酰吡嗪缩肼基甲酸甲酯的铜和锌配合物的晶体结构及荧光性质（英文）

Cu(Ⅱ) and Zn(Ⅱ) Complexes Based on Methyl (1-(3-Ethylpyrazin-2-yl)ethylidene)carbazate:Crystal Structures and Fluorescence Properties

合成并通过单晶X射线衍射、元素分析及红外光谱表征了配合物[Cu(HL)Cl_2]·H_2O(1)和[ZnL_2](2)的结构(HL为3-乙基-2-乙酰吡嗪缩肼基甲酸甲酯)。单晶衍射结果表明,在配合物1中,Cu(Ⅱ)离子拥有四方锥配位构型,与一个中性配体HL和2个氯离子配位。配合物2中,Zn(Ⅱ)离子与来自2个阴离子配体L-的N_2O电子供体配位,配位构型为扭曲的八面体。此外还研究了配合物1和2的固体荧光性质。

Two complexes, namely[Cu（HL）Cl2]·H2O （1） and[ZnL2] （2） （HL=methyl （1-（3-ethylpyrazin-2-yl）ethylidene） carbazate） have been synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. X-ray diffraction analysis results show that in complex 1, the Cu（Ⅱ） ion with a distorted square pyramid coordination geometry is coordinated with one neutral ligand HL and two chloride anions. However, the central Zn（Ⅱ） ion in complex 2 is surrounded by two independent anionic ligands with N2O donor set, thus possesses a distorted octahedral coordination geometry. The luminescent properties of the complexes were also studied in detail.
