- Abstract
We have measured the electron paramagnetic resonance spectra of genuine-organic anion-radical salts [Me-2,6- di-Me-Py](TCNQ)2, [Me-3,5-di-Me-Py](TCNQ)2, [N-Me-OH-Me-Py](TCNQ)2, [N-Et-OH-Me-Py](TCNQ)2, and metal-organic anion-radical salt [Mn-phen3](TCNQ)2∙H2O in the temperature range from 2 K to 300 K in the X-band frequency range. A comparison study of the shape of spectra, g-factors and linewidths with respect to the composition and crystal structure of studied compounds is presented. While the genuine-organic anion-radical salts display a typical EPR response originating from TCNQ pairs, the spectra of metal-organic anion-radical salt are dominated by the contribution of transition metal.
