The chemical effect of the electron capture of /sup 57/Co isotope in solid organic complexes was studied as a function of dimeric and monomeric structures of the same molecule as well as a function of the environment of the molecule in crystalline solid and frozen solutions of the same molecule. The /sup 57/Co was prepared in the forms of CO(III)-HEDTA and Fe(III)-HEDTA. In crystalline /sup 57/Co(III)-HEDTA dimer the daughter /sup 57/Fe of two valency states was observed in the ratio 75 percent to 25 percent. Results of the study indicate that the stabilization of /sup 57/Fe/sup n+/ is influenced not only by the immediate environment of the decayed nuclei but also by the environment of the whole molecule.
