Luminescent properties of the supramolecular complex, [Re(bpy)(CO)3{py-CH[CH(COOMe)2]2}]+(3, bpy = 2,2′-bipyridine), containing a novel ionophore precursor, py-CH[CH(COOMe)2]2(1), with two adjacent dimethyl malonate moieties joined together by a pyridine substituted methylene bridge, are found to respond selectively to Ba2+upon deprotonation of the two malonate moieties.
