Abstract

Among the large variety of highly conductive DCNQI-salts with metallic counterions, only Cu- and Tl-DCNQI exhibit NMR behavior like the metals Cu and Tl, respectively, i. e. considerable Knight shifts and longitudinal relaxation rates of Cu and H nuclei. Whereas in the copper salts there is no frequency dependence of the proton spin-relaxation rate, T-1 1H of Tl-DCNQI is proportional to w-1/2 pointing to a preferential 1-d electron spin-motion.
