Single-crystal X-ray diffraction has shown that the high-critical-temperature (T{sub c}) phase of the filamentary molecular superconductor (BEDT-TTF){sub 2}Ag(CF{sub 3}){sub 4}(1,1,2-trichloroethane) [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene] contains layers of BEDT-TTF radical cations with alternating {kappa}- and {alpha}'-type packing motifs. This molecule-based superconductor with dual BEDT-TTF packing motifs has a T{sub c} five times higher than that of its polymorph that contains only {kappa}-type packing.
