Aldehyde-decorated 2,2′-bipyridine and 2,2′:6′,2″-terpyridine ruthenium(II) complexes: Convenient scaffolds for supramolecular chemistry

Two new aldehyde-decorated tpy and bpy-containing ruthenium(II) complexes, [Ru(1)(bpy)2][PF6]2 and [Ru(1)(tpy)Cl][PF6] in which 1 is 5,5′-bis(4-formylphenyl)-2,2′-bipyridine, have been prepared and fully characterized. The packing in both solid state structures involves extensive Oaldehyde···HCpyridine contacts, but π-stacking interactions are important only between [Ru(1)(tpy)Cl]+ cations.

The syntheses, solution spectroscopic properties and single crystal structures of two new aldehyde-decorated tpy and bpy-containing ruthenium(II) complexes, [Ru(1)(bpy)2][PF6]2 and [Ru(1)(tpy)Cl][PF6] (1 = 5,5′-bis(4-formylphenyl)-2,2′-bipyridine) are described.Figure optionsDownload as PowerPoint slide
