在水热条件下合成了3个配合物,[Cd0.5(o-bix)NO3]n(1),[Cd(m-bix)2(H2O)2·2NO3]n(2)和[Cd(2,3-pidc)(p-bix)]n(3)(bix=二(1-亚甲基咪唑)取代苯,2,3-pidc=2,3-二羧基吡嗪)。配合物1具有一维链状结构,配合物2具有双重相互平行穿插的结构,配合物3则是二维平面结构。同时,对配合物1～3进行了热稳定性和荧光性质的研究。配合物1的结构在215℃以下是稳定的。配合物2从82到150℃失去参与配位的水分子。配合物3在273℃以下结构保持稳定。在室温下,360nm处的荧光激发导致配合物1、2、3分别在450、460、460nm处有荧光发射。
Three complexes of [Cd0.5 (o-bix) NO3] n (1), [Cd (m-bix) 2 (H2O) 2 · 2NO3] n (2) and [Cd (2,3-pidc) (p-bix)] n (3) (bix = bis (1-methyleneimidazole) substituted benzene, 2,3-pidc = 2,3-dicarboxypyrazine). Complex 1 has a one-dimensional chain structure, complex 2 has a double structure parallel to each other interspersed, complex 3 is a two-dimensional planar structure. Meanwhile, the thermal stability and fluorescence properties of complexes 1 ~ 3 were studied. The structure of complex 1 is stable below 215 ℃. Complex 2 lost water molecules involved in coordination from 82 to 150 ℃. The structure of complex 3 remained stable at 273 ℃. Fluorescence excitation at 360 nm at room temperature resulted in the fluorescent emission of complexes 1, 2, 3 at 450, 460, 460 nm, respectively.
