摘　　要：A new ionic pair complex,1,2′-dinithile-1,2′-dithiolene nickel(II) containing substituted benzylpyridinium [Bz(Me)Py]2[Ni(mnt)2],is prepared and characterized by elemental analyses,IR,UV-VIS and single crystal X-ray diffraction.Where [Bz(Me)Py]+ was 1-(1′-phenylethyl)-pyridinium and mnt2-is 1,2′-dinithile-1,2′-dithiolene.The crystal structure was solved by direct method and refined by full-matrix least-squares methods for All the nonhydrogen atoms.The final R1 and wR2 for all data were 0.0450 and 0.1236,respectively.The complex is composed of two [Bz(Me)Py]+ cations and a [Ni(mnt)2]2-anion.The [Ni(mnt)2]2-anions form a stepwise structure by π-π stacking interactions between the CN groups.The cation-anion C-H···N hydrogen bonds and cation-cation C-H···π interactions give further rise to a network structure.A new ionic pair complex, 1,2′-dinithile-1,2′-dithiolene nickel （Ⅱ） containing substituted benzylpyridinium [ Bz （Me） Py] 2[ Ni （mnt）2 ], is prepared and characterized by elemental analyses, IR, UV-VIS and single crystal X-ray diffraction. Where [ Bz （Me） Py ]^＋ was 1-（ 1 ′-phenylethyl）-pyridinium and rant2 is 1,2′-dinithile-1, 2′-dithiolene. The crystal structure was solved by direct method and refined by full-matrix least-squares methods for All the nonhydrogen atoms. The final R1 and wR2 for all data were 0.0450 and 0.1236, respectively. The complex is composed of two [ Bz （Me） Py ] ^＋ cations and a [ Ni （rant） 2 ] ^2- anion. The [ Ni （mnt） 2 ]^2- anions form a stepwise structure by ,π-π stacking interactions between the CN groups. The cation-anion C-H… N hydrogen bonds and cation-cation C-H…π interactions give further rise to a network structure.
