Abstract

The Cs+ salts of radical anions (DMTCNQ^-·, DETCNQ^-· and TNAP^-·) of dimethyl- and diethyl-substituted tetracyanoquinodimethanes (DMTCNQ and DETCNQ), and tetracyanonaphthoquinodimethane (TNAP) were prepared, which have molecular formulae of Cs⁺·DMTCNQ^-·, {Cs⁺·DETCNQ^-·/ (Cs⁺·DETCNQ^-·)· 1/2 DETCNQ} and (Cs⁺·TNAP^-·)· 1/2 TNAP, respectively. The {Cs⁺·DETCNQ^-·/ (Cs⁺·DETCNQ^-·)· 1/2 DETCNQ} and (Cs⁺·TNAP^-·)· 1/2 TNAP salts exhibited considerably high room-temperature electrical conductivities (σ_RT's) of ca. 0.1 S·cm^-1 on the compressed pellets. The room-temperature ferromagnetic behavior was observed for the three Cs⁺ salts, of which large saturation magnetization (7.3 emu·mol^-1) was obtained for the (Cs⁺·TNAP^-·)· 1/2 TNAP salt.
