Abstract

The spectrum of th ethylenediammonium salt of the dimeric Fe(III) comples ion [(HEDTAFe)2O]2- was examined. The ultravloIet absorption spectrum of this isolated metal complex containing the bridging unit Fe(lII)···O···Fe(III) slows several bands due to the simultaneol!s electronic excitation of the two Fe(III) centers. The band positiors are in excelient agreement with calculated sums of one-center d-d transitions.
