• The electrical resistivity measurements for the novel organic superconductor k-(BEDT-TTF)_2Cu(CN)[N(CN)_2] (T_c=11.2 K) [BEDT-TTF represents bis (ethylenedithiolo)tetrathiafulvalene] under pressure or in high magnetic field were studied. Several physical parameters, such as the superconducting transition temperature (T_c), the depressibility of T_c with pressure (-dT_c/dP), the residual resistance ratio (RRR), the upper critical field (H_<C2>), and the effective Ginzburg-Landau mass anisotropy between perpendicular and parallel to the conducting plane (m_<⫽>/m_<⊥>), are determined. They are discussed in comparison with those of other κ-type organic superconductors with T_c above 10 K ; k-(BEDT-TTF)_2Cu(NCS)_2 and k-(BEDT-TTF)_2Cu[N(CN)_2]Br. A simple relation was observed between these parameters (T_c, -dT_c/dP and RRR) and the dimensionality of the electronic structures of these superconductors.
