Abstract

A novel spin-crossover molecular conductor, [Fe(qnal)2][Pd(dmit)2]5.acetone, was prepared and characterized. The crystal structural analyses of both the low- and high-temperature phases revealed that the supramolecular pi-pi interactions between the spin-crossover Fe(qnal)2 cations as well as the cation contraction play an important role in the uniaxial lattice deformation which will modulate the electrical conductivity of the conducting Pd(dmit)2 layer.

摘要

制备并表征了一种新型自旋交叉分子导体[Fe(qnal)₂][Pd(dmit)₂]·丙酮。低温相和高温相的晶体结构分析表明，自旋交叉Fe(qnal)₂阳离子之间的超分子π-π相互作用以及阳离子收缩在单轴晶格变形中起重要作用，这种变形将调节导电Pd(dmit)₂层的电导率。
