Polycrystalline [4-NH_2C_5H_4NH] SbCl_4 and [4-NH_2C_5H_4NH] SbCl_6 have been investigated by proton NMR methods between 120 K and 370 K under hydrostatic pressure of 0.1 and 520 MPa. Reduction in the dipolar second moment is interpreted in terms of cation reorientation. Activation energies characterizing the motion increase with increasing pressure.
