报道了一种含磁性单阴离子八甲基二茂铁二磺酸盐[-O_3S-C_5(CH_3)_4Fe+C_5(CH_3)_4-SO_3-(Ofds)]，α-(bedt-ttf)_5(Ofds)_2的新型半导体电荷转移盐的结构和性质。该盐为半导体，ρRT=5.6 × 10 3Ω cm，a=0.11 eV。不仅在二茂铁基上，而且在2D施主层上也存在两种类型的自旋。前一种自旋和后一种自旋分别服从居里-魏斯模型(C=0.721 emu K -1和θ=-5.5K)和二维海森堡模型(j2dH=-80.3K)。
The structure and properties of a new semiconducting BEDT‐TTF‐based charge‐transfer salt containing the magnetic monoanion octamethylferrocenedisulfonate [–O3S‐C5(CH3)4Fe+C5(CH3)4‐SO3–(ofds)], α‐(BEDT‐TTF)5(ofds)2is described [BEDT‐TTF = bis(ethylenedithio)tetrathiafulvalene]. The salt is a semiconductor withρRT= 5.6 × 103Ω cm andEa= 0.11 eV. There are two types of spins not only on the ferrocenyl parts but also on the 2D donor layers. The former and latter spins obey the Curie–Weiss (C= 0.721 emu K mol–1andθ= –5.5 K) and 2D Heisenberg (J2DH= –80.3 K) models, respectively.
