Extended x-ray absorption fine structure studies on the manganese contained in spinach chloroplasts and on certain di-..mu..-oxo-bridged manganese dimers of the form (X/sub 2/Mn)O/sub 2/(MnX/sub 2/) (X = 2,2'-bipyridine and 1,10-phenanthroline) are reported. From these studies, the manganese associated with photosynthetic oxygen evolution is suggested to occur as a bridged transition-metal dimer with most likely another manganese. Extensive details on the analysis are included.
