59 Co‐ and 1 H‐NMR. spectra as well as preparative work have shown that oxygenation of solutions of triethylenetetramine cobalt(II) leads to a mixture of isomeric forms of [Co 2 (trien) 2 μ (O 2 , OH)] 3+ . Using a new preparative method, starting from mononuclear cobalt(III)‐chelates, a binuclear μ‐peroxo‐cobalt(III) complex has been obtained in two different forms, where the chelate configuration is predominantly either α‐cis or β‐cis in both centres. The two configurations can be distinguished by IR. spectroscopy.
