The present paper describes the preparation and characterization of some potassium ion complexes with 1,4,7,10,13,16,-hexaoxacyclooctadecane having six donar oxygen atoms. The potassium metal compounds used for complexation are salts of nitrophenols and 8- hydroxyquinoline. Products were isolated from potassium salt of all the four monoionic ligands, 2-nitrophenol (ONPH), 2,4-dinitrophenol (DNPH), 2,4,6-trinitrophenol (TNPH) and 8-hydroxyquinoline (8HQH) with 18-crown-6 ether. It was found that potassium salts and 18-crown-6 ether did bind together, rather than they remain uninteracted. The products 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.
