A binuclear tetrahedral zinc(II) complex of 2-(2-pyridyl)benzo[1,2-d;4,5-d′]diimidazole with strong blue fluorescence
摘要:
A binuclear Zn(II) complex: Na[Zn-2(pbdiim)Cl-5] (.) 1.5 H2O (pbdiim = 2-(2-pyridyl)benzo[1,2-d,4,5-d']diimidazole) (1) has been prepared and the crystal structure determined by single-crystal X-ray diffraction. The pbdiim ligand coordinates to two zinc ions in which each zinc ion adopts a distorted tetrahedral geometry. Complex I has a more planar structure and displays strong blue fluorescence at room temperature than the pbdiim molecule. (C) 2004 Elsevier B.V. All rights reserved.
