Abstract
The Cs+ salts of radical anions (DMTCNQ(-.), DETCNQ(-.) and TNAP(-.)) of di methyl- and diethyl-substituted tetracyanoquinodimethanes (DMTCNQ and DETCN Q), and tetracyanonaphthoquinodimethane (TNAP) were prepared, which have mo lecular formulae of Cs+. DMTCNQ(-.), (Cs+. DETCNQ(-.)/(Cs+. DETCNQ(-.)). 1/ 2DETCNQ) and (Cs+. TNAP(-.)) 1/2TNAP, respectively. The(Cs+. DETCNQ(-.)/(Cs +. DETCNQ(-.)). 1/2DETCNQ) and (Cs+. TNAP(-.)). 1/2TNAP salts exhibited con siderably high room-temperature electrical conductivities (sigma(RT)'s) of ca. 0.1 S.cm(-1) on the compressed pellets. The room-temperature ferromagne tic behavior was observed for the three Csf salts, of which large saturatio n magnetization (7.3 emu.mol(-1)) was obtained for the (Cs+. TNAP(-.)). 1/2 TNAP salt.
