The simplified model approach is applied to low-energy collisions of iron atoms and cations with hydrogen atoms and anions.Inelastic collisional processes for all transitions involving 97 low-lying covalent Fe + H states and two ionic ${\text{Fe}}^{+}$ + ${\text{H}}^{-}$ molecular states are treated, and rate coefficients for excitation, de-excitation, ion-pair formation and neutralization processes are calculated within the ${}_6{\mathrm{\Sigma }}^{+}{}_6\mathrm{\Pi },{}_6\mathrm{\Delta },{}_4{\mathrm{\Sigma }}^{-},{}_4\mathrm{\Pi },{}_4\mathrm{\Delta }$ and ${}^4\mathrm{\Phi }$ molecular symmetries.Rate coefficients with highest values correspond to the mutual neutralization processes ${\text{Fe}}^{+}$($3{\text{d}}^6$4s ${}^6\text{D}$) + ${\text{H}}^{-}\to$ Fe($3{\text{d}}^6$(³G)4s4p(³P°) w ⁵G°, v ⁵F°, y ⁵H°) + H(1s ²S) and ${\text{Fe}}^{+}$($3{\text{d}}^7{}^4$F) + ${\text{H}}^{-}\to$ Fe($3{\text{d}}^7({}^2$G) 4p w ³F°, y ³H°, v ³G°) + H(1s ²S). The highest rate coefficients for excitation and de-excitation correspond to the Fe($3{\text{d}}^6$(³G)4s4p(³P°) v ⁵F°) + H($1\text{s}$ ²S)$\to$ Fe($3{\text{d}}^6$(³G)4s4p(³P°) y ⁵H°) + H(1s ²S) process within the sextet molecular symmetries and the Fe($3{\text{d}}^7$(²${\text{D}}_2$)4p v ³F°) + H($1\text{s}$ ²S) $\to$ Fe($3{\text{d}}^7$(²G)4p v ³G°) + H(1s ²S) process within the quartet molecular symmetries.
