Structural variety and magnetic properties of oxime-bridged copper(II) complexes

• Oxime-bridged copper(II) complexes were synthesized.
• The products display different nuclearities.
• Nuclearity and arrangement of the complex molecules is driven by different templating anions.
• Structural aspects are described in detail.
• IR/EDX spectroscopic studies were performed.

A series of new oxime-bridged copper(II) complexes is introduced with phenyl 2-pyridyl ketoxime (ppkoH) as a ligand: polymeric [Cu2(ppko)2(ppkoH)2](NO3)(BF4)·CH3OH (1), dinuclear [Cu2(ppko)2(ppkoH)2](ClO4)2 (2), [Cu2(ppko)2(ppkoH)](ClO4)2·0.75CH3OH (3), trinuclear [Cu3(OH)(ppko)3(CH3OH)]·[Cu3(OH)(ppko)3(CH3OH)2](ClO4)4·CH3OH (4) and [Cu3(OH)(ppko)3(CH3OH)](BF4)(NO3) (5). Structural aspects are described in detail, other characterization techniques include elemental analyses, IR and EDX spectra.

A series of oxime-bridged copper(II) complexes with different nuclearities is presented, displaying a variety of structures driven by the presence of various templating anions.Figure optionsDownload as PowerPoint slide
