Magnetoresistance of the tittle organic metal, where BO is bis (ethylenedioxy)-tetrathiafulvalene, is investigated. The angle dependent oscillations indicate the existence of cylindrical Fermi surface, and the observed periodicity is consistent with the calculated band structure. The amplitude of the oscillation is very small in the direction where the Fermi surface touches the zone boundary. The thermoelectric power is zero in the whole temperature range in all directions, suggesting effectively a half-filled situation of the band structure.
