Figure 4 First coordination sphere about the MnIII ions Mn2, Mn3, and Mn4 of 1. a) Mn2 with distorted square pyramidal geometry b) Mn3 with Λ configuration c) Mn4 with planar configuration and DMF bound (0.51 (1) occupancy) d) Mn4 with planar configuration and 1-methylimidazole bound (0.49 (1) occupancy). The thermal ellipsoid plots are at a 50% probability level. Hydrogen atoms have been omitted for clarity. |
