| Abstract: The ion pair complex (NO2Ql)2 ((NO2Ql)+=1-(4-nitrobenzyl)-quilorinium; mnt2-=maleonitriledithiolate) has been prepared, characterized by elementary analysis and IRspectrum. The crystal structure determination of this complex shows: Triclinic, space group with a=8.2240(16)Å,b=10.777(2)Å,c=12.137(2)Å,α=72.58(3)°,β=72.82(3)°,γ= 68.78(3)°,V=935.4(3)Å3 and Z=1. The most prominent general structural features of the complex are the completely segregated stack columns of [Ni(mnt)2]2- anions and [NO2Ql]+ cations. The [Ni(mnt)2]2- anions form uniform one dimensional chain within the anion column, and there are weak π…π stacking interactions between neighbor cations. |
