What is Dioxygen-bridged and monomeric cobalt(III) complexes with 1,3-Diamino-2-(aminomethyl) propane and ethylenediamine about?

Use of ethylenediamine (en) and the tripod ligand I,3-diamino-2-(aminomethyl)propane (daap) results in cobalt(III)-pentamine complexes with obligate configuration. Optimization of the synthesis of ((en)-(daap)Col,0z4+ suggests that daap must undergo conformational change for complete coordination. Ultraviolet and visible spectra of [(en)(daap)Co],0z4+, [(en)(daap)Co]zO,'+, [Co(daap)(enOH]z+, and [Co-(daap)(en)HzOJ" are consistent with those of similar complexes. NA4R spectra for [(en)(daap)CoJ,0a4' and for paramagnetic [(en)(daap)Co],0z5+ were observed and assigned. The aqueous acidity of the cation [Co(daap)(en)HzO]3' was obtained at various ionic strengths.
