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)Cl2]· H2O (1)和[ZnL2](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N2O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.CCDC:1544291,(H2L)NO3;1544292,1;1544293,2.
