| 摘要: 通过水热方法,以5-氯烟酸(5-ClnicH)和2,2'-联咪唑(2,2'-biimidazole)分别与Zn(NO3)2·6H2O和Cd(NO3)2·4H2O反应,合成了2个配合物[Zn(5-Clnic)2]n (1)和[Cd(5-Clnic)2(H2biim)2] (2),并对其结构和荧光性质进行了研究。结构分析结果表明配合物1和2分别属于单斜晶系,C2c空间群和三斜晶系,P1 空间群。配合物1具有二维层状结构,而且这些层通过Cl…Cl卤键作用进一步形成了三维超分子框架。2为单核镉配合物,通过分子间N-H…O、C-H…N和C-H…Cl氢键作用,单核的分子被进一步连接成了三维超分子结构。配合物1和2在室温下能分别发出很强的紫色和绿色荧光。 |

| Abstract: Two coordination compounds, namely [Zn(5-Clnic)2]n (1) and [Cd(5-Clnic)2(H2biim)2] (2,5-ClnicH=5-halonicotinic acid, H2biim=2,2'-biimidazole), were assembled. Single-crystal X-ray diffraction analyses revealed that the two complexes crystallize in the monoclinic system, space group C2c and triclinic system, space group P1, respectively. Compound 1 possesses a 2D sheet coordination network, which is further extended into a 3D supramolecular architecture via Cl…Cl halogen bonding. Compound 2 consists of a mononuclear molecule, which is assembled to a 3D supramolecular framework through N-H…O, C-H…N and C-H…Cl hydrogen bond. Luminescent of both compounds have also been studied.
