The chemistry of manganese has received considerable attention in recent ye
ars due to the fact that manganese is believed to be catalytically active i
n a variety of metalloenzymes. This paper deals with the study of homo- and
mixed-valence EPR active trinuclear manganese complexes potential models f
or the polymanganese oxo centers. (C) 1999 Elsevier Science S.A. All rights
