Cover Picture (Angew. Chem. Int. Ed. Engl. 19/1994)

33_19/1994The cover picture shows a ball-and-stick model of the first peroxocopper(II) complex [(Cu4L2)(O2)(OMe)2(ClO4)]+ (L = anion of the tridentate ligand 4-methyl-2,6-bis-(pyrrolidinomethyl)phenol) stable at room temperature. This cation (color code: Cu brown, O red, N blue, C black, Cl green) is characterized by several unusual structural details, including a μ4-bridging O2 ligand and a ClO4 ligand bound unsymmetrically to the Cu4 center. The picture was produced with the program POV-Ray on a IBM Workstation by Dipl.-Chem. S. J. Schindler, Further information on the structural and spectroscopic properties of this compound, which are of general interest for biochemistry and coordination chemistry, are reported by B. Krebs and J. Reimm on pages 1969ff.
