摘要

A charge-transfer compound, [NO(2)BzPz][Ni(mnt)(2)] (NO(2)BzPz( ) = 1-(4'-nitrobenzyl)pyrazinium and mnt(2-) = maleonitriledithiolate). has been structurally characterized, which shows rare noncovalently intermolecular interactions between lone-pair electron and electron-deficient pyrazine rings (NO2 center dot center dot center dot pi and CN center dot center dot center dot pi), theoretical analysis reveals that such intermolecular interactions can be attributed to Coulomb interaction. The paramagnetic [Ni(mnt)(2)](-) anions in [NO(2)BzPz][Ni(mnt)(2)] form a dimerized stack and strong antiferromagnetic coupling interaction is observed in such a spin dinner which lead to weak paramagnetic feature in this compound.
