Synthesis and Co(III) complexes of the new tetradentate mixed-donor tetraamine ligand N-{2-[(2-pyridin-2-ylethyl)amino]ethyl}ethane-1,2-diamine (peda)

The syntheses of the new linear tetradentate tetraamine ligand N-{2-[(2-pyridin-2-ylethyl)amino]ethyl}ethane-1,2-diamine (peda) and some Co(III) complexes of this ligand are reported. An X-ray crystal structure of [Co(peda)O2CO]I · H2O and kinetic data for the acid hydrolysis of [Co(peda)(O2CO)]ClO4 · H2O are detailed.
