Figure 2 Single-crystal structure of [(tpy)Ru(tppz)Ru(tpy)](PF6)4×4MeCN, with all counterions and solvent molecules included. Also shown is the observed disorder in two of the PF6- anions (P2,F7-F12 and P4,F19-F24) and one of the MeCN solvent molecules (N13,C55,C56). Displacement ellipsoids are drawn at th e 50% probability level. H atoms are omitted for clarity.  [article HTML]
