Popis: | Mossbauer spectroscopy of iron(III)bis(dicarbollide) (1) and its adduct (2) revealed low spin FeIII in 1 and supprasingly FeII in 2. In 1 the (C2B9H11) rotate at room temperature with 107 Hz frequency getting across energy barrier of 24 meV. Numerical simulations shown a gradient of electric charge in 2 which may explain the FeII-like character in 2. |
