  Effect of anions on cadmium(II) complexes with ligand 2-(pyrazin-2-yl)-1H-benzimidazole

  摘要：

  Three new supramolecular complexes based on a 2-(pyrazin-2-yl)-1H-benzimidazole (Hpbi) and a series of Cd(II) salts have been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction analysis. Reaction of CdCl2 center dot 2.5H(2)O with Hpbi afforded a one-dimensional chain [Cd(Hpbi)Cl-2] (1), which exhibits a three-dimensional (3-D) supramolecular architecture through intermolecular X-H center dot center dot center dot Cl (X = N and C) hydrogen bonds and pi-pi stacking interactions. When using CdBr2 center dot 4H(2)O instead of CdCl2 center dot 2.5H(2)O under similar reaction conditions, a bisnuclear complex [Cd(Hpbi)(2)Br-2] (2) is obtained, which obviously exhibits intermolecular X-H center dot center dot center dot Br (X = N and C) hydrogen bonds and pi-pi stacking interactions. When CdI2 take place of CdCl2 center dot 2.5H(2)O, a mononuclear complex, [Cd(Hpbi)(2)I-2] (3), is isolated, which shows a 3D supramolecule framework formed by intermolecule hydrogen bonds and pi-pi packing interactions. Interestingly, the Hpbi ligand exhibits the same coordination modes in complexes 1-3. It is noteworthy that the radius of anions plays an important role in affecting the structures and luminescent intensity of the final products. The TGA for 1-3 have been investigated and discussed in detail. (C) 2011 Elsevier B.V. All rights reserved.
