Temperature dependent locally resolved 13C Knight shifts in the organic conductor TTF[Ni(dmit)2]2
2014 High resolution 13C NMR results for the organic conductor TTF[Ni(dmit)2]2 enriched by 13C isotope in Ni(dmit)2 molecules are reported. Variable temperature magic angle spinning experiments were performed between 160 and 295 K. Paramagnetic Knight shifts in the range 41-106.5 ppm at room temperature are observed for all Ni(dmit)2 carbon sites. These shifts are slightly temperature dependent...
متن کاملINFRARED NEAR-ISOTROPY IN A MIXED STACK ORGANIC CONDUCTOR: OMTSF-Ni(DMIT)2~
From transport measurements the mixed stack organic conductor OMTSF-Ni(DMIT) 2 (OMTSF: bistetramethylene-TSF, Ni(DMIT)2: (4,5-dimercapto-l,3-dithiole-2-thione)nickel) is known to possess near isotropy in the crystallographic a-c plane, where there are indeed a large number of close interstack contacts in different directions. A study is presented of the polarized infrared reflectance spectra fo...

The two new radical anion salts I McPh,P][Pd(dmitL, I, (1) (dmit=C,S~ 2 = i,3-dithiole-2-thione-4,5-dithiolate) and [PhtPII Pd tdmi t ) : l , (2) have been synthesized and characterized by X-ray diffraction, elemental analysis and temperature-dependent conductivity measurements. Complexes I and 2 were prepared via electrooxidation of [ Pd( dmit ): I 2 in acetonitrile-acetone solvent mixtures at...
متن کاملOptical and transport studies of Ni(dmit)2-based organic conductors.
Single-crystal Ni~dmit!2 salts, ~Ph4P!@Ni~dmit!2#3 , ~Bu4N!2@Ni~dmit!2#7•2CH3CN, and ~Me3S!@Ni~dmit!2#2 , have been synthesized. All show semiconducting behavior in their temperature-dependent dc conductivities. Room-temperature polarized reflectance measurements have been made over the range between 100 and 32 000 cm ~12 meV–4 eV!. For light polarized along the Ni~dmit!2 stacking axis, all spe...
