Abstract

A new bidentate polypyridine bridging ligand (biphen), produced by the condensation of 1,10-phenanthroline-5,6-dione with 5,6-diamino-phenanthroline has been synthesized and characterized. In addition the monometallic complex [(bpy)₂Ru^II(biphen)](PF₆)₂ and the bimetallic complex [(bpy)₂Ru^II(biphen)Ru^II(bpy)₂](PF₆)₄ have been prepared. The complexes were characterized by elemental analysis, by ¹H-NMR spectroscopy and by cyclic voltsmmetry(CV).

The results of these analyses seem to indicate that biphen acts like two independent units when attached to a - Ru^II(bpy)₂ fragment. a bipyridine portion and a phenazine portion. Moreover, CV data on the bimetalllic complex indicated no special stability for the mixed-valence form, ruling out any significant metal-metal interaction.
