ESR observations were performed for the ternary complexes formed with Na<SUP>+</SUP>–TCNE<SUP>−</SUP> and 5<I>O</I>-crown ethers. The temperature dependence of the observed Na hyperfine line width was analyzed by applying Bloch's twojump model, and the thermodynamical parameters of the complex formation were determined. The stability of the ternary complexes were found to be much affected by the substitution of either the fused benzene ring or the 2,2′-biphenyldiyl group, which acts as a steric restriction during the optimum metal binding to the flexible crown ring.
