Figure 3 First coordination sphere about each Mn(III) ion of 1. a) Mn2 with planar configuration b) Mn3 with distorted square pyramidal geometry c) Mn4 with distorted square pyramidal geometry d) Mn5 with [Delta] configuration and e) Mn6 with planar configuration. The thermal ellipsoid plots are at a 50% probability level. Hydrogen atoms have been omitted for clarity. The disordered atoms of the imidazole attached to Mn2 are only shown at the higher occupancy positions.  [article HTML]
