Crystals of (BEDT-TTF)(n)X(m), where X is an anion having magnetic moment, have different stoichiometries and structural motifs depending on the size of the anions and their coordination geometry. Their electrical properties are predominantly semiconducting except for one salt which is metallic down to 200mK. The magnetic properties of the large gap semiconducting salts are dominated by the moments on the metal anions and do not show any observable interaction between the spin systems [e.g. for (BEDT-TTF)2FeCl4 theta is -6K). Those of small gap semiconductors indicate there is some exchange [e.g. for (BEDT-TTF)6(CuBr4)2 theta is -107K). In the case of the metallic salt, (BEDT-TTF)3 CuCl4.H2O, the interaction between the two independent spin systems is small (theta is similar to +1K).
