摘要：

This work is devoted to the study of compounds [M(N-4)](TCNQ)(n), where N-4 = saturated or unsaturated tetraazamacrocycles, TCNQ = 7,7,8,8-tetracyanoquinodimethane, n = 2, 3. The metal is coordinated to two TCNQ groups only when there is coordinative unsaturation oil it. When n = 2 all the TCNQ units are radical anions and no charge delocalization is observed. In the compounds with n = 3 only 2/3 of the TCNQ are negatively charged and a greater charge delocalization is possible: This delocalization only appears when none of the TCNQ's are coordinated to the metal and it is reflected in the higher conductivity values obtained in the solid state.
