摘要: Three title metal complexes of [Cu(H2O)4(CH3COO)2(H2L)2] (1), [(Mn(H2L))2Cl4(H2O).5(H2O)] (2) and [Cu3(CH3COO)2(CH3OH)(H2L)2] (3) have been synthesized characterized by X-ray single-crystal analyses, elemental analysis, infrared spectrum, UV–Vis absorption spectra fluorescence spectra, which are based on a flexible ligand 3,5-dibromosalicylaldehyde diethylenetriamine (H2L) diffusion method. Crystallographic analysis show that for complex 1, the infinite 1D square sheets arrange regularly to form 2D channels O–H⋯O bonds, 2 can spatial structure through coordination effect, π–π accumulation van der Waals force intermolecular weak H-bonds, 3 is self-assembled via stacking, Weals H-bonds with various modes center Cu ions.
