A neutral copper complex flanked by two protonated 4,5-diazafluoren-9-one (
dafone, 1) ligands which are H-bonded with water molecules and perchlorate
anions has been structurally and electrochemically characterized. The cappe
d copper compound remains intact in solution, exhibiting a reversible Cu(II
)/Cu(I) couple although undergoing a deformation along the Cu-N(2) axis and
can serve as a good model of ionic pockets with metal active sites in some
metalloproteins. (C) 2001 Elsevier Science B.V. All rights reserved.
