摘要：

A series of chiral bimetallic complexes have been prepared containing both Cu(II) and Hg(11) metal centers. The complexes possess chiral salen ligands which host Cu(11) in the center of the cis-N2O2 chromophore and Hg(H) via two oxygen atoms of the chromophore. Halogen and acetate groups from mercury salts interact with the Cu(11) center. The X-ray crystallographic data of 11 reveals a short distance of (ClCu)-Cu-... (3.22-3.26 Angstrom). EPR study also discloses a strong interaction, in particular, of acetate group with Cu. (C) 2003 Published by Elsevier B.V.
