the diffusion of tetrathiafulvalene (TTF) and [NBun4]2[PtCl6] in acetonitrile. Crystals (black plates) are tetragonal, space group P4/mbm, with a=11.757(2), c=11.707(2) A, and Z=2. The block-diagonal least-squares refinement, based on 804 independent reflections with ∣Fo∣> 3σ(F), yields an R factor of 0.11. The structure is comprised of TTF-trimer units which are arranged perpendicularly to each other

四硫富瓦烯(
TTF)和[NBun4] 2 [PtCl6]在
乙腈中的扩散制备了标题盐。晶体(黑色板)是四边形,空间群P4 / mbm,a = 11.757(2),c = 11.707(2)A,Z = 2。基于-Fo∣>3σ(F)的804个独立反射进行块对角最小二乘优化,得出的R因子为0.11。该结构由彼此垂直排列的
TTF-三聚体单元组成,形成了二维层,三聚体之间的
硫-
硫接触有些紧密。该盐在25°C下的压实小颗粒的电阻率为87Ωcm。[PtCl6] 2-阴离子的
