Synthesis,Crystal Structure and Properties of a Cadmium Complex containing 2,5-Thiophene Dicarboxylic Acid and 1,1'-(1,4-Butanediyl) Bis(imidazole)

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。

A mononuclear cadmium compound, [ Cd（bbi） （tdc） （H2O）]n · nH2O [bbi： 1, 1＇-（ 1,4- butanediyl） his（imidazole） ; H2tdc： 2,5-thiophene dicarboxylic acid] was synthesized at room temperature in the mixed solvent. Its structure was determined by single-crystal X-ray diffraction analysis, and further characterized by IR spectra and elemental analysis. In addition, the thermal stability and the luminescent property of [ Cd（bbi） （tdc） （H2O） ]n· nH2O have been investigated in detail. The titled complex crystallizes in orthorhombic system, space group Fdd2 witha=20.945（2） A, b =32.309（4） A, c = 12. 1084（14） A, α=90°, β=90°, γ=90°, V= 8194. 1 （16） A3, C16H20 C dN4O6S, Mr = 508. 82, Z = 16, Dc = 1. 650 g. cm -3, F （ 000 ） = 4096, the final R1 = 0. 0186, wR2 =0. 0491. The Cd ion was coordinated with carboxyl oxygen atoms from H2tdc ligands to form a onedimensional （1D） linear chain, and ultimately formed a 3D structure by bbi ligands.
