We have performed magnetoresistance measurements along the least conducting (Formula presented) direction in (Formula presented) under 6 kbar pressure while the magnetic field was rotated in the (Formula presented) plane. Here 6 kbar is sufficient to suppress the (Formula presented) ordering transition observed at ambient pressure. Comparison with similar experiments on anion-ordered (Formula presented) and with (Formula presented) allow the following conclusions: The periodicity is ill defined in the (Formula presented) but not the (Formula presented) direction in the presence of anion disorder, the disorder has a small to negligible effect on the scattering rate along (Formula presented) and the anion ordering is not responsible for previously observed differences in angular-dependent magnetoresistance in these sister salts.
