摘要

To explore the coordination possibilities of anthracenebased ligands, three cadmium(II) complexes with anthracene-9-carboxylate (L) and relevant auxiliary chelating or bridging ligands were synthesized and characterized: Cd _2(L)_4(2bpy)_2(μ-H_2O (1), Cd _2(L)_4(phen)_2(μ-H_2O) (2), and {[Cd_3(L)_6(4bPy)]}~∞ (3) (2bpy = 2, 2'bipyridine, phen = 1, 10-phenanthroline, and 4bpy = 4, 4'-bipyridine). Structural analyses show that complexes 1 and 2 both take dinuclear structures by incorporating the chelating 2bpy or phen ligand, which are further interlinked by intermolecular hydrogen-bonding, TI-JI stacking, and/or C-H?π supramolecular interactions to generate higher-dimensional supramolecular frameworks. Complex 3 has a onedimensional (ID) ribbon-like structure, which is further assembled into a two-dimensional (2D) layer, and a three-dimensional (3D) framework by the co-effects of interchain C-H?O hydrogen-bonding and C-H?π supramolecular interactions. Moreover, the luminescent properties of these complexes were further investigated in detail.
