More Information on the
[(1,4,7-tris(2-aminophenyl)1,4,7-triazacyclononane)Cu(II)]2+ Ion
The [(1,4,7-tris(2-aminophenyl)1,4,7-triazacyclononane)Cu(II)]2+ ion (with multiple bonds) is shown on the left. The ligand contains three bidentate subunits tethered together to yield a single hexadentate ligand. The ligand is neutral and binds to the Cu(II) ion through lone pairs on each N atom. The overall charge on the complex is therefore +2.
