Superconductivity is discovered in new type of two-dimensional organic metal κ-(BEDSe-TTF)₂CuN(CN)₂Br consisting of BEDT-TTF donor analogue having selenium-substituted six-member outer rings. This salt is isostructural to the corresponding BEDT-TTF salt and shows metallic behavior accompanied with a spin-density-wave transition at T_MI ∼ 25 K. The application of pressure up to 0.15 GPa generates superconducting state at T_c = 7.5 K, which is lower than T_c of the BEDT-TTF salt (T_c = 11.6 K). The lowering of T_c and the modification in the electronic structure are explained in terms of the important contribution of selenium electrons and the concomitant enhancement in donor dimerization.
