Figure 3 . Three-dimensional structure of the title complex. The red dashed lines represent π–π stacking interactions,while blue dashed lines indicate F(BF4−)⋯π(pyrazinyl) interactions. A, B, C and D red lettering indicate Cg2⋯Cg2i,Cg3⋯Cg3ii,Cg4⋯Cg4iii and Cg1⋯Cg1iv distances, respectively, while E represents F4⋯Cg1v distance. (See Table 2). |
