Abstract
The preparation of (TMTSF)(2)Ni(tht)(2), tht=thiete or [bis(trifluorom ethyl)ethylene] dithiolate, single crystals and their preliminary char acterization by electrical resistivity, thermopower, EPR and magnetic susceptibility are reported. The transport properties indicate a metal lic behaviour at high temperatures (sigma(RT)approximate to 50 S/cm, S -RT=1 mu V/K) and a metal to insulator transition at 69 K. The overall behaviour is similar to that previously reported for the beta-phase o f the selenium analogues (TMTSF)(2)M(tds)(2). M=Ni and Pt.
