In this paper, we report transport measurements of interlayer magnetoresistance with field parallel and perpendicular to the current direction in an all organic superconductor {beta}{sup {double_prime}}-(BEDT-TTF){sub 2}SF{sub 5}CH{sub 2}CF{sub 2}SO{sub 3}. For H{parallel}I, the isothermal magnetoresistance R(H) at low temperatures (T{le}T{sub c}) displays a peak effect as a function of field. For H{perpendicular}I, R(H) increases monotonically with increasing field. The results are very analogous to the interlayer magnetoresistance in {kappa}-(BEDT-TTF){sub 2}X compounds. The observation of the peak effect or negative magnetoresistance in different systems for H{parallel}I{perpendicular} plane suggests that it is intrinsic to the layered organic superconductors. For H{perpendicular}I, the large positive magnetoresistance is in a general agreement with a two band model for charge transport. {copyright} {ital 1999} {ital The American Physical Society}
