Temperature-dependent 57Fe Mossbauer 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+ cation has been elucidated in a transverse magnetic field experiment at room temperature.
