Cores for thought! A new [Mn4 O4 ]6+ "cubane" core complex (L6 Mn4 O4 ) with six facially bridging phosphinate chelate ligands (L- =(MePh)2 PO2- ) was synthesized. Photo-excitation releases molecular O2 by intramolecular coupling of two core oxygen atoms and selective rearrangement to a [Mn4 O2 ]6+ "butterfly" core ([L5 Mn4 O2 ]+ ; see scheme). Thus the Mn4 O4 cubane core exhibits unique reactivity in O2 evolution which may account for its presence in the photosynthetic enzyme.
