摘要: 用溶剂热法合成了含混合配体的双核镉配合物[Cd2(BHP)2(2,6-pda)2(H2O)2]·H2O(BHP=吡啶2,6-二甲酰肼,2,6-H2pda=吡啶-2,6-二甲酸),用红外光谱和元素分析对配合物进行了表征。X-射线单晶结构分析表明,该配合物属于三斜晶系,空间群为Pī,晶胞参数:a=0.999 70(13) nm,b=1.038 00(15) nm,c=1.077 40(16) nm,α=115.601(3)°,β=110.510(3)°,γ=98.416(2)°,V=0.883 7(2) nm3,Z=1。配合物中的两个Cd(Ⅱ)离子都处于七配位的五角双锥几何构型中,配合物通过分子间的氢键作用形成了三维超分子结构,并对配合物的荧光性质进行了研究。

Abstract: A binuclear complex [Cd2(BHP)2(2,6-pda)2(H2O)2]·H2O with mixed ligands was synthesized from the solvothermal reaction (BHP=pyridine-2,6-dicarbohydrazide and 2,6-H2pda=pyridine-2,6-dicarboxylic acid) and it is characterizedby IR and elemental analyses.The results of single-crystal X-ray diffractionanalysis show that the title complex crystallizes in the triclinic space groupPī with a=0.999 70(13) nm,b=1.038 00(15) nm,c=1.077 40(16) nm,α=115.601(3)°,β=110.510(3)°,γ=98.416(2)°,V=0.883 7(2) nm3,Z=1.In the title complex,each Cd(Ⅱ) ion is seven-coordinated in distorted pentagonal bipyramidal geometry.Three-dimensional supramolecular is formed by hydrogen bonding interaction in the title complex.Fluorescent properties of the title complex wasinvestigated.

Key words: complex, synthesis, structure, fluorescence
