The title compound 1 is a model for the Mn 3 IIIMn IV center near the photosystem II. It follows from the dependence of the susceptibility of 1 on temperature and field strength that its magnetic properties are determined both by ferromagnetic as well as antiferromagnetic interactions and that the ground state has a spin of 9/2. The first excited states should be more than 200 cm −1 energy‐richer than the ground state.
