The crystal structure and electronic and magnetic properties of magnetic molecular conductor (EDTDM)_2FeBr_4 are investigated. The material undergoes a SDW transition at T_<MI>∿11 K and an antiferromagnetic transition of Fe^<3+> d-spins at T_N=3 K. In addition to the appearance of an anomaly in the resistivity around T_N, a large magnetoresistance is observed below T_N, which diverges at the critical pressure (P_c∿9.2 kbar) of the MI transition. The perturbation potential from the antiferromagnetic Fe^<3+> spin arrangement stabilizes the SDW state, leading to the anomaly in the resistivity. The application of magnetic field reduces the potential of the Fe^<3+> spins, which leads to the large negative magnetoresistance. This indicates that the π-d interaction plays an important role in the interplay between the magnetism and the electron transport.
