چکیده انگلیسی
An anion-radical salt (ARS) (N-Me-2,5-di-Me-Pz)(TCNQ)2, where Pz is pyrazine, was synthesized and its crystal structure was resolved. X-ray diffraction experiments on single crystals were performed. Heat capacity was measured in the temperature range from 2 to 300 K. Magnetisation and magnetic susceptibility were measured in the temperature range from 2 to 300 K and the low-temperature part was measured in magnetic fields from 5 mT to 5 T. The experimental results were explained in terms of dimerized Heisenberg spin 12 chain model. Numerical calculations were performed and compared with experimental data.
