The present paper describes the preparation and characterization of some strontium ion complexes with 1,4,7,10,13,16,-hexaoxacyclooctadecane (18-crown-6 ether) having six donar oxygen atoms. The strontium metal compounds used for complexation are salts of nitrophenols and 8-hydroxyquinoline. Attempts were made to isolate products from strontium salt of all the three monoionic ligands, 2,4-dinitrophenol (DNPH), 2,4,6-trinitrophenol (TNPH) and 8-hydroxyquinoline (8HQH) with 18-crown-6 ether. It was found that strontium salts and 18-crown-6 ether did bind together, rather than they remain uninteracted. The product in each procedure was chromotographed using TLC. The TLC products were used to identify the interaction and formation of stable compounds. The bonding pattern and structure of complexes were suggested from the studies of elemental analysis, IR, UV and 1H-NMR spectral analysis.
