Notes:
A variety of new organo-molecular magnets have been characterized in our and colleagues' laboratories in recent years using classic susceptibility measurements. In this effort, iron-57 Mössbauer spectroscopy has proven a particularly useful additional tool in elucidating charge transfer and interesting, unprecedented magnetic behavior for magnets based on electron donation from decamethylferrocene to polycyanide electron acceptors, e.g., tetracyanoethylene, tetracyano-quino-dimethane, hexacyanobutadiene. Examples of Mössbauer spectra of such systems are presented with emphasis on (a) slow paramagnetic relaxation at low spin ferric sites as a probe for spin on the polycyanide electron acceptor units; (b) large orbital contributions to internal hyperfine fields concommitant with highly anisotropic magnetic behavior; and (c) onset of multiple hyperfine pattern spectra signifying complex magnetostructural transformations.
