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 (σRT'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.
