Dicopper(II) complexes of chiral C2-symmetric diamino-bis(2-methylpyridyl) and diamino-bis(2-methylbenzimidazolyl) ligands
摘要:
Reaction of the chiral ligands (1S,4S)-2,5-bis(6-methylpyridyl)-diazabicyclo[2.2.1]heptane (L-1), and (1S,4S)-2,5-bis(2-methylbenzimidazolyl)-diazabicyclo[2.2.1]heptane (L-2) with copper(II) acetate results in the hydroxo-bridged dicopper complexes [(L-1)Cu-2(mu-OH)(H2O)(OAc)(2)Cl] (1-Cl center dot H2O), and [(L-2)Cu(mu-OH)(H2O)(MeOH)(OAc)(2)]OAc (2H(2)O,MeOH). Both chiral complexes were characterized spectroscopically, as well as in the solid state by X-ray crystallography. (C) 2010 Elsevier B.V. All rights reserved.
