The structure and properties of a new semiconducting BEDT‐TTF‐based charge‐transfer salt containing the magnetic monoanion octamethylferrocenedisulfonate [ – O 3 S‐C 5 (CH 3 ) 4 Fe + C 5 (CH 3 ) 4 ‐SO 3 – (ofds)], α‐(BEDT‐TTF) 5 (ofds) 2 is described [BEDT‐TTF = bis(ethylenedithio)tetrathiafulvalene]. The salt is a semiconductor with ρ RT = 5.6 × 10 3 Ω cm and E a = 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 –1 and θ = –5.5 K) and 2D Heisenberg ( J 2DH = –80.3 K) models, respectively.
