Syntheses, structures and catecholase activity of two cobalt(III) complexes derived from N,N′-ethylenebis(3-ethoxysalicylaldiimine): A special host-guest system from a special ligand

Syntheses, characterization, catechol oxidase activity and electrospray ionization mass spectroscopy of two mononuclear cobalt(III) compounds derived from the Schiff base double compartmental ligand N,N′-ethylenebis(3-ethoxysalicylaldiimine) are reported. Unique features of the two compounds in terms of showing catechol oxidase activity and, more importantly, some unique structural features of one of the two compounds have been discussed.
