Common name for N , N' -ethylenebis(salicylideneaminato)cobalt(II). It was synthesized in 1933 by P. Pfeiffer, Tokuichi Tsumaki and others and reported that it changed color to a dark brown in air, and in 1938 Tsumaki discovered that this color change was due to oxygen absorption. Its properties as an oxygen carrier were subsequently studied in detail by M. Calvin and H. Diehl and others. It can be prepared by adding a freshly prepared aqueous solution of cobalt(II) acetate to an ethyl alcohol solution of ethylenediamine, heating the mixture, and then adding salicylaldehyde.
