anion-binding. Luminescent complexes of the form [Ru(bipy)2L]2+, [ReL(CO)3Cl] and [RuL(CN)4]2− were prepared and some were structurally characterised; their interactions with various guest species were investigated by luminescence and NMR spectroscopy. For complexes with the crownethers (L1 and L2), binding of K+ was rather weak, but the electrostatic effect due to the charge on the host complex was clear with

in good yield, a series of ligands in which a phenanthroline binding site is attached to an adjacent crown ether unit; the NN chelating site may be coordinated to Ru(bipy)2}2+ units to afford [Ru(bipy)3]2+ derivatives with pendant crown ether units, which can bind alkali metal ions.
