本文研究了κ相有机导体和超导体中给电子分子的分子堆积排列。（BEDT-TTF）2X（X <$I3 −，Cu（NCS）2−），κ-（MDT-TTF）2AuI2，而κ-（BMDT-TTF）_2Au（CN）_2]的研究表明，超导电性的主要预测因素似乎是（i）键-环内二聚体分子堆积和（ii）相对较短的（图3.35A）二聚体内分离。新发现的κ相有机导体中的这些结构特征可能是发生常压超导的必要条件。
Abstract An examination of the molecular packing arrangements of the electron-donor molecules in κ-phase organic conductors and superconductors [κ-(BEDT-TTF)2X (X ˭ I3−, Cu(NCS)2−), κ-(MDT-TTF)2AuI2, and κ-(BMDT-TTF)2Au(CN)2] reveal that the main predictors of superconductivity appear to be (i) bond-over-ring intradimer molecular packing and (ii) relatively short (∼ 3.35A) intradimer separations. These structural features in newly discovered κ-phase organic conductors may be requirements for the occurrence of ambient pressure superconductivity.
