Corrigendum: Fe₂Si₅N₈: Access to Open-Shell Transition-Metal Nitridosilicates

In Figure 4 of this Communication, Fe²⁺ was assigned as high-spin. In fact, the Mössbauer spectroscopic measurements do not allow to distinguish between high- and low-spin states in Fe₂Si₅N₈. However, according to the spin-only formula, the observed value of 3.2(1) μ_B indicates approximately two unpaired electrons and thus low-spin states of Fe²⁺ (d⁶) for the present heavily distorted tetrahedral environments. No part of the quintessence in the Communication is affected. The authors sincerely apologize for this misassignment.
