The crystal structure and low-temperature transport properties of the recently synthesized {kappa}{sup '}-(BEDT-TTF){sub 2}Cu[N(CN){sub 2}]Cl radical cation salt are investigated. The crystals exhibit metallic conductivity and are ambient-pressure superconductors with critical temperature in the range (11.3-11.9) K. The crystals show some distinctions in structure as compared to that of the Mott insulator {kappa}-(BEDT-TTF){sub 2}Cu[N(CN){sub 2}]Cl: smaller size of the unit cell and deficiency in the occupancy of the copper positions. Anisotropy of superconducting properties as well as a nontrivial temperature dependence of the upper critical field were observed.
