常温下,以溶液法合成了一个单核结构的镉配合物[Cd(bbi)(tdc)(H2O)]n·n H2O(bbi:1,4-双(咪唑-1-基)丁烷;H2tdc:2,5-噻吩二羧酸),通过单晶X-射线衍射、红外光谱、元素分析对其进行了结构表征,并研究了配合物的热稳定性和荧光性质。配合物属于正交晶系,空间群Fdd2,晶胞参数:a=20.945(2),b=32.309(4),c=12.1084(14),α=90°,β=90°,γ=90°,V=8194.1(16)3,C16H20CdN 4O6S,Mr=508.82,Z=16,Dc=1.650 g·cm-3,F(000)=4096,R1=0.0186,wR2=0.0491。来自tdc配体的羧基氧原子与Cd离子配位形成1D直线型链,并通过含氮配体bbi与Cd离子配位最终形成了3D结构。
At room temperature, a Cd (bbi) (tdc) (H2O)] n · n H2O (bbi: 1,4-bis H2tdc: 2,5-thiophene dicarboxylic acid) was synthesized and characterized by single crystal X-ray diffraction, FTIR and elemental analysis. The thermal stability and fluorescence properties of the complex were also studied. The complex belongs to the orthorhombic system with space group Fdd2. The unit cell parameters are a = 20.945 (2) , b = 32.309 4, c = 12.1084 14, α = 90 °, γ = 90 °, V = 8194.1 (16) 3, C16H20CdN 4O6S, Mr = 508.82, Z = 16, Dc = 1.650 g · cm -3, F (000) = 4096, R1 = 0.0186, wR2 = 0.0491. The carboxyl oxygen atoms from the tdc ligand coordinate with the Cd ions to form a 1D linear chain and form the 3D structure through coordination of the nitrogen-containing ligand bbi with Cd ions.
