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 ion-pair complex,[2-Na(Me)IQl]2[Ni(i-mnt)2],was obtained by the direct reaction of K2(i-mnt)(i-mnt=iso-maleonitriledithiolate),NiCl2·6H2O and [2-Na(Me)IQl]Br([2-Na(Me)IQl]+=1-(2′-naphthylmethyl)isoquinolinium) in MeOH.Its composition and structure were characterized by elemental analyses,IR,UV-VIS and single crystal X-ray diffraction.The single crystal structure analysis revealed that the complex is composed of two [2-Na(Me)IQl]+ cations and a [Ni(i-mnt)2]2-anion,and forms a network structure through C-H…N,C-H…(hydrogen bonds and π…π stacking interaction.
