title: (N-Me-2,6-di-Me-Pz) (TCNQ)(2)-genuine organic anion-radical salt: a spin-ladder?
abstract: The room temperature Raman spectra investigations on single crystals of an anion-radical salt (N-Me-2,6-di-Me-Pz) (TCNQ)(2) with a pyrazine-based cation were performed. The infrared reflection spectra of the sample were recorded in the frequency range from 400 to 7500 cm(-1), at room temperature. Magnetization measurements were performed as a function of temperature in magnetic fields up to 5 T. The heat capacity and magnetic susceptibility were measured in the temperature range from 2 to 300 K. The results are studied in terms of quasi-one-dimensional magnetic theoretical models and they indicate behavior close to a spin-ladder system.
