A novel BEDT-TTF-based purely organic magnetic conductor, α - (BEDT - TTF)2(TEMPO - N(CH3)COCH2SO3) ⋠3H2O

A new BEDT-TTF-based salt with an organic free radical TEMPO has been prepared. The salt consists of alternate layers of conducting and magnetic sheets, between which are short S(BEDT-TTF) …O(TEMPO) contacts. The magnetic susceptibility is well modelled by the combination of a 2D Heisenberg and a Curie-Weiss model with J=−89K and θ=+0.05K.
