摘要：

Tetracyanoethylene (TCNE) reacts in aprotic dimethoxyethane solution with a cesium metal mirror to yield black crystals of [TCNE.-Cs+].infinity. The solvent-free radical salt C6N4CS crystallizes in the monoclinic system P2(1)/n with Z = 8, fw 261.0, a = 858.39 (40) pm, b = 1762.76 (90) pm, c = 1030.49 (50) pm, and beta = 93.43 (4)-degrees; R(w) = 3.6%. It contains staples of two differently structured TCNE.- radical anions with two different cesium countercations, which are coordinated to eight and nine nitrogens. The crystal structure is compared to those of the respective sodium and potassium salts as well as to cesium pentacyanopropenide and cesium tetracyanoquinodimethanide.
