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。
The binuclear cadmium complex [Cd2 (BHP) 2 (2,6-pda) 2 (H2O) 2] · H2O (BHP = pyridine 2,6-dicarboxylhydrazide, 2 , 6-H2pda = pyridine-2,6-dicarboxylic acid). The complexes were characterized by FTIR and elemental analysis. The X-ray single crystal structure analysis shows that the complex belongs to the triclinic system with space group Pī, with the unit cell parameters of a = 0.999 70 (13) nm, b = 1.038 00 (15) nm and c = 1.077 40 ( Α = 115.601 (3) °, β = 110.510 (3) °, γ = 98.416 (2) °, V = 0.883 7 (2) nm3, Z = 1. The two Cd (Ⅱ) ions in the complex are in a seven-coordinate pentagonal bipyramidal geometry. The complex formed a three-dimensional supramolecular structure by intermolecular hydrogen bonding and the fluorescence properties of the complex the study.
