Stabilization of the daughter species following the Auger event in some cobalt(III) chelates in different matrices

Abstract

The emission Moessbauer spectra of [$sup 57$Co(III)(phen)$sub 3$](ClO$sub 4$)$sub 3$.2H$sub 2$O and [$sup 57$Co(III)(bpy)$sub 3$](ClO$sub 4$)$sub 3$.3H$sub 2$O dispersed in matrices of sucrose, poly(ethylene oxide), and the corresponding Fe(II) chelates were studied. The ratio of the Fe(II)/Fe(III) species stabilized varies from matrix to matrix. These observations have been interpreted on the basis of electron acceptor and donor centers. (auth)
