Anion-radical salts (ASR) of 7,7,8,8-tetracyanoquinodimethane (TCNQ) were the first organic objects to exhibit metallic properties [1]. After the discovery of ability of TCNQbased ARS to melt without decomposition in the middle of 1980s the wide application possibilities in electronics were revealed. The discovery of new applications encouraged further research of these materials. The discovery of new aplications of TCNQ-based ARS encouraged further research of these materials. The structure and magnetic properties of both, genuine organic ARS and ARS with cation containing metallic atom are investigated. [2,3] The correlations between crystal structure and structure of magnetic subsystem were studied also in our previous papers by examining magnetic and thermodynamic properties of genuine organic ARS based on TCNQ molecules. We have observed major impact of structure of cation molecule on the magnetic properties of ARS. While the magnetic structure of sample (N-Me-2,5-di-Me-Pz)(TCNQ)2 (Pz is pyrazine) can be described with a dimerized Heisenberg spin ½ chain model [4], the sample (N-Me-2,6-di-Me-Pz)(TCNQ)2, where cation is just an isomer of the previous one, can be described by spin-ladder model [5]. The study of sample (N-Me-3,5-di-MePy)(TCNQ)2 showed two energy gaps in magnetic excitations spectra, which corresponds to two types of structure dimers [6]. In the presented work we report the synthesis of novel genuine organic ARS (N-Me2,6-di-Me-Py)(TCNQ)2,.The magnetic properties were studied by measurement of susceptibility in temperature range 2 – 300 K, in magnetic fields 10 mT, 100 mT, and 1 T using ZFC and FC modes.. The analysis of magnetic susceptibility indicates, that the magnetic system can be described by Heisenberg spin ½ chain model with small amount of free spins. The low-temperature peak can be explained by interchain coupling which may lead to spin-Peierls transition.
