Abstract
- New di- and tetranuclear Cu(II) complexes, [Cu<subscript>2</subscript>(HL)Cl<subscript>2</subscript>(MeOH)]·MeOH·2CH<subscript>2</subscript>Cl<subscript>2</subscript> (1) and [Cu<subscript>4</subscript>(L)<subscript>2</subscript>(MeOH)<subscript>2</subscript>](NO<subscript>3</subscript>)<subscript>2</subscript>·EtOH (2), have been synthesized from CuCl<subscript>2</subscript>·2H<subscript>2</subscript>O, Cu(NO<subscript>3</subscript>)<subscript>2</subscript>·3H<subscript>2</subscript>O and a symmetric 5-bromosalicylaldehyde-decorated bis(salamo)-like ligand (H<subscript>3</subscript>L, (1E,3E)-2-hydroxy-5-methylisophthalaldehyde O,O-di(2-((((E)-5-bromo-2-hydroxybenzylidene)amino)-oxy)ethyl)dioxime), and characterized by elemental analyses, IR and UV–vis spectra. Single crystal structure analyses showed a dinuclear Cu(II) structure for 1 and a tetranuclear Cu(II) structure for 2. In 1, two Cu(II) ions are on one side of the double N<subscript>2</subscript>O<subscript>2</subscript> cavities, and the phenol proton in the other cavity is attached. In 2, four Cu(II) ions are located in four N<subscript>2</subscript>O<subscript>2</subscript> cavities of two fully deprotonated L<superscript>3−</superscript> units, giving a centrosymmetric double helix structure. The Hirshfeld surfaces analyses, Interaction Region Indicator (IRI), and DFT computations of H<subscript>3</subscript>L, 1, and 2 were studied. In addition, the electrochemical and fluorescence properties of 1 and 2 were also investigated. [ABSTRACT FROM AUTHOR]
