    Angular magnetotransport measurements have been performed to tackle the origin of the magnetoresistance in the quasi-one-dimensional hollandite Ba 1.2 Rh8 O16. Three samples of different impurities amount were measured. We observe that the low-temperature resistivity upturn is not due to a charge-density wave transition and a dominant role of impurities scattering for low-temperature transport properties is instead demonstrated. The components of magnetoresistance were separated by using the Kohler plot and the angular dependency of the resistance under magnetic field. It shows the major contribution of an isotropic, likely spin driven, negative magnetoresistance. Galvanomagnetic characteristics are then consistent with a Kondo effect and appear to be essentially three dimensional at low temperature.
