摘要

Ammonium ferric hexacyanoferrate is a veterinary-medical milestone and antidote against radiocesium, well-known as Giese-salt after the Chernobyl disaster fed to domestic and wild animals, which shows even a rich interplay of properties in nanostructural chemistry and ferromagnetism. Among the broad analytical techniques, the ambivalence of macroscopic micrometer-sized agglomerates and nanoparticle sizes, a suggested enlarged \(\text {Fe}^{\textrm{II}}{-}\text {C}\equiv \text {N}{-}\text {Fe}^{\textrm{III}}\) Fe II - C N - Fe III bond length by Fe K-edge XAFS results and multi-level spin relaxation in \(^{57}\) 57 Fe Mössbauer spectroscopy are highlighted. This sets this underestimated compound in a new light, e.g., for modern biomedicine and biofunctionality, extending its essential importance in addition to hypothetical future nuclear incidents.
