摘　　要：合成了两种新的有机盐 [NO2 BzPy]Cl(1)和 [NO2 BzPyNH2 ]Cl(2 ) ,(1) [或 (2 ) ]与K[TCNQ]2 进一步反应生成 [NO2 BzPy][TCNQ]2 (3)和 [NO2 BzPyNH2 ][TCNQ]2 (4)。光谱数据表明 :TCNQ盐中存在TCNQ0和TCNQ-,并形成了一维TCNQ分子柱 ,且TCNQ0 和TCNQ-之间存在相互作用 ,部分电荷从 [TCNQ]-2向阳离子 ([NO2 BzPy]+ 和 [NO2 BzPyNH2 ]+ )转移。TCNQ (TCNQ= tetracyanoquinodimethane) salts have good conductivity. The magnetic properties of substituted benzylpridiniums, such as ferromagnetism, antiferromagnetism and spin Peierls transition, have widely been investigated. In order to obtain some new materials with both conductivity and magnetism, two new organic salts, [NO(2)BzPy] Cl (1) and [NO(2)BzPyNH(2)]Cl (2), were synthesized and characterized. Further more, two new charge transfer salts, [NO(2)BzPy] [TCNQ](2) (3) and [NO(2)BzPyNH(2)] [TCNQ](2) (4) were synthesized and characterized. The tested results of elementary analysis of charge transfer salts (3) and (4) were consistent with theoretical values, and the results of IR indicated that there exist TCNQ and TCNQ anions. One-dimensional molecular column of TCNQ has been formed. Partial charge transfer takes place from [TCNQ](2)(-) to cation.
