Electrical and Magnetic Properties of (BEDT-TTF)4Ni(CN)4 Complex

The electrical conductivity and the ESR spectra of the single crystal of (BEDT-TTF)4Ni(CN)4 complex were measured. This crystal exhibits a metal–insulator transition at 160 K. The ESR signals show the presence of the [NiIII(CN)4]− anion in addition to the BEDT-TTF cation radical. The spin concentrat...

More Information
Summary:The electrical conductivity and the ESR spectra of the single crystal of (BEDT-TTF)4Ni(CN)4 complex were measured. This crystal exhibits a metal–insulator transition at 160 K. The ESR signals show the presence of the [NiIII(CN)4]− anion in addition to the BEDT-TTF cation radical. The spin concentration of Ni(III) ion was estimated to be 0.01 of the total Ni ions from the temperature dependence of the spin susceptibility of these components. The X-ray photoelectron spectra were also taken.
