摘要: 通过水热合成的方法得到1个由苯骈咪唑-5-羧酸(HL)配体构筑的Cd(Ⅱ)配合物[Cd(L)2(H2O)]n。在配合物中,镉中心为变形的八面体配位构型。每个配体连接着2个镉原子,每个镉原子通过4个配体相互连接,在bc面上形成以平行四边形为基本结构单元的二维层状结构,层与层之间通过N-H…O和O-H…O氢键连接形成三维超分子网络结构。此外,我们还研究和讨论了配合物的固态荧光性质。 |

Abstract: A Cd(Ⅱ) complex, [Cd(L)2(H2O)]n (1), based on benzimidazole-5-carboxylic acid (HL) ligand has been hydrothermally synthesized. The Cd(Ⅱ) atoms have a distorted octahedron coordination geometry. Each L ligand links two Cd(Ⅱ) atoms and each Cd(Ⅱ) atom attaches to four L ligands to form a two-dimensional (2D) layer structure along bc plane, which consists of regular parallelograms, then yield a three-dimensional (3D) supramolecular network by N-H…O and O-H…O hydrogen bonds. The TGA and luminescence property in solid state of complex 1 have been further studied and discussed in this paper. CCDC: 722775. |
