摘要

A novel anion-radical salt, (Bbzim)(TCNQ) _1.5·CH ₃CN (1), (where Bbzim = 1,3-bis(4-cyanobenzyl)-1H-imidazol-3-ium and TCNQ = 7,7,8,8-tetracyanoquinodimethane) has been fabricated and X-ray single crystal structural analyses. The structure analysis show there exist TCNQ ^-1 and TCNQ ⁰ entries, which are in agreement with the IR spectra analysis of the compound. Two TCNQ (A) and one TCNQ (B) molecules stack into a triad, and the triads further develop into a column in a pattern ···ABA···ABA··· along a-axis. The temperature dependence of the magnetic susceptibility (2-300 K) for 1 exhibits spin gap of singlet-triplet feature, and the best fit gave the Δ/k _B = 1236.5 K.
