Figure 2
(a) Illustration of the asymmetric unit rendering the disorder of the hexafluoridophosphate anions and acetonitrile solvate molecules (see Refinement section for details). An additional π–π stacked [Ru(L–N4H2)tape]2+ cation demonstrates, due to the view along the normal of the tape ligand's r.m.s. plane, the nearly face-to-face π–π stacking motif between the tape ligand moieties. The atomic numbering is shown for the anions and solvent molecules as well as for the ruthenium atoms. Hydrogen atoms are omitted for clarity. [Symmetry codes: (ii) 1 − x, −y, 1 −z, (ix) 1 −x, 1 −y, −z.] (b) A side view of the dimer formed by two [Ru(L–N4H2)tape]2+ in [Ru(L–N4H2)tape](PF6)2·1.422CH3CN, featuring the stacking interactions via planar tape ligand moieties. Only H atoms essential for illustration of the hydrogen bonds, shown as orange dashed lines, are included. |
