摘要: 以5-氨基-1H-1,2,4-三唑-3-羧酸(HAtca)为配体,通过水热法和溶液扩散法分别合成了2个新的配合物[Zn(Athy) Br]n(1,HAthy=5-氨基-1H-1,2,4-三唑-3-醇)和[Mn(Atca)2(H2O)2](2)。单晶结构分析表明配合物1和2分别属于正交和单斜晶系,结晶于Pbca和P21/c空间群。配合物1为2D层状结构,2是单核配合物。在配合物1中不存在氢键,而配合物2中含有丰富的氢键作用,并且通过氢键的作用形成了一个三维的网格结构。同时在固态下,配合物1和2分别在360、462 nm和382、402 nm处有较强的荧光发射峰。 |

Abstract: Two coordination polymers[Zn(Athy)Br]n (1, HAthy=5-amino-1H-1,2,4-triazol-3-ol) and[Mn(Atca)2(H2O)2] (2, HAtca=5-amino-1H-1,2,4-triazole-3-carboxylic acid) were separately synthesized by hydrothermal method and solution diffusion method using HAtca, ZnBr2 and MnCl2, respectively. X-ray single crystal diffraction analyses indicate both 1 and 2 have different crystal structures. Complex 1 crystallizes in the orthorhombic system, space group Pbca. Complex 2 crystallizes in the monoclinic system,space group P21/c. Complex 1 is a 2D grid structure without any hydrogen bonds, but complex 2 has a 3D grid structure constructed by highly stable hydrogen bonds. Moreover, 1 and 2 show strong fluorescence emission at 360, 462 nm and 382, 402 nm at room temperature, respectively. |
