A new biradical of nitronyl nitroxide, 1,3-[di-2-(4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl-1-oxyl-3-oxide)phenoxy]propane [BNITPhOPr (1)], was prepared and characterized. The temperature dependence of the magnetic susceptibility values were observed for 1 in the range of 2-300 K. The observed data was successfully simulated giving the exchange integral J = -0.47 cm-1, q = -0.94 K. This result indicates a weak antiferromagnetic spin exchange interaction between the biradicals. - 英文摘要: --
