Temperature-dependent <SUP>57</SUP>Fe Mössbauer effect spectroscopy has been used to characterize the hyperfine and dynamical properties of the metal atom in two crystallographic forms of ferrocenium hexafluoroarsenate. The temperature dependence of the recoil-free fraction and the spin-lattice relaxation rates have been determined over the interval 89<T<300 K and shows a small difference between the two crystallographic forms. The sign of the quadrupole splitting parameter in the Fc<SUP>+</SUP> cation has been elucidated in a transverse magnetic field experiment at room temperature.
