摘要：
The crystal structures of two bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) superconductors, kappa-(BEDT-TTF)2Cu(CN)[N(CN)2] and kappa'-(BEDT-TTF)2Cu2(CN)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 ''cores'' 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.
