[Preparation and spectroscopic study of two new charge transfer salts].
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, [NO2BzPy]Cl (1) and [NO2 BzPyNH2]Cl (2), were synthesized and characterized. Further more, two new charge transfer salts, [NO2BzPy] [TCNQ]2 (3) and [NO2BzPyNH2] [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.
