CRYSTAL-STRUCTURE OF U-HYDROXO-BIS[TRIS(2-AMINOETHYL)AMINE]DICOPPER(II) PERCHLORATE

A novel, high-symmetry dicopper complex bridged by only a single hydro xo has been synthesized and structurally characterized. The coordinati on geometry of copper(II) is a strict trigonal bipyramidal of C-3 upsi lon symmetry. The three equivalent amino nitrogen atoms of the ligand form the equatorial plane, while the tripodal nitrogen atom and the hy droxo anion occupy axial positions. The bridging Cu-(OH)-Cu angle of t he single hydroxo anion is only 136.5 degrees, which does not agree we ll with data found in similar compounds. The magnetic-structural relat ion is discussed.
