The preparation of bipartite ligands bridged by e.g., aromatic polycydes, such as pyrene, falls within the second category - the so-called synthesis at the complex 

58 was prepared from 0.090 g (0.104 mmol) of 57, following the procedure described above for preparation of the mononuclear [RuL ] complexes. Purification was performed by chromatography on alumina with CH3CN/H2O/KNO3 (80/16/
