摘要：
(Figure Presented) On a reduced charge: The reduction of 1,2,4,5-tetracyanobenzene (TCNB) with tetrakis(dimethylamino)ethylene (TDAE) forms [TDAE][TCNB]3·MeCN. Characterization reveals that the [TDAE]2+ ion is present, and that TCNB is reduced forming diamagnetic [TCNB]32-. The reduced TCNB units (see picture) are best described as [TCNB]≈0.5-[TCNB]≈1--[TCNB] ≈0.5- containing fractionally charged organic species. © 2006 Wiley-VCH Verlag GmbH &. Co. KGaA.
