| 摘要: 通过水热反应合成了一种新颖的镉-联咪唑化合物[Cd(BIm)2](ClO4)(OH)·2H2O(1)(BIm=2,2'-biimidazole),并对其进行了单晶X-射线衍射结构表征。该化合物具有孤立结构特征,镉原子与4个氮原子配位形成1个扭曲的四面体。光致发光研究发现该化合物发出蓝色荧光。理论研究结果显示该荧光来自于LMCT机理。本文还对其红外光谱进行了报道。 |

| Abstract: Anovel cadmium-biimidazole compound [Cd(BIm)2](ClO4)(OH)·2H2O (1) (BIm=2,2'-biimidazole) has been synthesized via a hydrothermal reaction and structurally characterized by single-crystal X-ray diffraction. Compound 1 features an isolated (0D) structure with the cadmium ions coordinating to four nitrogen atoms to give a distorted tetrahedron. Photoluminescent investigation shows that compound 1 exhibits an emission in the blue region. Theoretical study reveals that the emission is ascribed to ligand-to-metal charge transfer (LMCT). The spectral data of FT-IR are also reported. CCDC: 895386. |
