The crystal structures of two bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) superconductors, [kappa]-(BEDT-TTF)[sub 2]Cu(CN)[N(CN)[sub 2]] and [kappa][prime]-(BEDT-TTF)[sub 2]Cu[sub 2](CN)[sub 3] have been determined. From this analysis, empirical rules have been formulated which can predict the donor packing motif and superconducting transition temperatures of ambient-pressure BEDT-TTF superconductors with planar anions. These rules show that the packing of the donor molecules is governed by a pattern of [open quotes]cores[close quotes] of openings in the anion layer. We find superconducting transition temperatures are roughly proportional to the volume of the space in which the carrier can delocalize effectively. 47 refs., 12 figs., 4 tabs.
