The line widths and spin–lattice relaxation times of protons in [N(C_(2)H_5)_4]_(2)CoCl_4 and [N(CH_3)_4]_2CoCl_4 single crystals were investigated in the temperature range 160–400 K. The temperature dependences of the spin–lattice relaxation times are attributed to the molecular motions of the ethyl and methyl groups in the [N(C_(2)H_5)_4]^+ and [N(CH_3)_4]^+ ions respectively. The NMR line widths indicate that the ethyl groups in [N(C_(2)H_5)_4]_(2)CoCl_4 have one more degree of freedom than the methyl groups in [N(CH_3)_4]_2CoCl_4. The experimental results are interpreted in terms of the reorientations of the methyl and ethyl groups.
