Tetranuclear Cu(ii)-chiral complexes: synthesis, characterization and biological activity.

ABSTRACT: Tetranuclear chiral Cu(ii)-Schiff-base complexes S-1 and R-1, were synthesised using enantiomerically pure (S)-(H₂vanPheol) and (R)-(H₂vanPheol) ligands respectively in the ratio of 1 : 1 of Cu(NO₃)₂ to (S/R)-(H₂vanPheol) in MeOH at room temperature. A pair of polynuclear chiral Cu(ii)-cluster complexes were characterized using single-crystal X-ray diffraction, elemental analysis, infrared and CD spectroscopy. The results revealed the importance of these chiral ligands encouraging the arrangement of copper metal in non-centrosymmetric polar packing. The potential of the novel [Cu₄(S/R-vanPheol)₂(S/R-HvanPheol)₂(CH₃OH)₂](NO
