A novel dimeric copper salicylate with an undissociated COOH group: Synthesis and crystal structure of [Cu2(HSal)(Sal)(2,2′-bpy)2](ClO4)
摘要:
A dinuclear copper salicylate [Cu-2(HSal)(Sal)(2,2'-bpy)(2)](ClO4) (1) (H(2)Sal = salicylic acid) has been synthesized and characterized with the aid of elemental analysis and infrared, ultraviolet and fluorescence spectroscopic studies. The molecular structure of 1, determined by single-crystal X-ray diffraction studies, shows the presence of incompletely deprotonated salicylate ligands in the complex. Hydrogen bonding interactions and pi-pi aromatic stacking lead to the formation of 2D polymeric structure in the solid state. (C) 2006 Elsevier B.V. All rights reserved.
