In this article we have reported the synthesis, characterisation and ion binding studies of a new RuII-polypyridyl-crown-anthraquinone complex (5). Studies confirm selective binding of BaII, SrII and CaII ions, with Kmath image &gt; Kmath image &gt;&gt; Kmath image, over all other metal ions, to the crown ether moiety and not to the methoxy anthraquinone component, the latter being the second binding site available and known for its affinity towards alkaline earth metal ions from one of our previous reports.</p>1 aBanerjee, Tanmay1 aSuresh, Moorthy1 aGhosh, Hirendra, N.1 aDas, Amitava  uhttps://library.ncl.res.in/content/competitive-binding-ba2and-sr2-18-crown-6-receptor-1-methoxyanthraquinone-analogue-other
