Figure 3
A packing plot, showing the close-packing of two hydrogen-bonded tapes of (II), viewed along the crystallographic c axis (a axis horizontal). Hydrogen bonds are shown as thin dashed lines. The η6-binding mode of the p-cymene ligands is represented by heavy dashed lines between the Ru atoms and the centroids of the aromatic ring. [Symmetry codes: (i) -x, -y, -z; (ii) -x+1, -y, -z+1.] |
