Abstract

Crown ethers have been used for the various studies pertaining to extraction equilibrium constant, stability constant and for determination of some of the alkali and alkaline earth elements and other elements from p, d and f-block elements. Crown ethers have a significant coordination power towards silver ion. The present paper describes synthesis and characterization of novel Ag(I) complexes with 1, 4, 7, 10, 13,-pentaoxacyclooctadecane (15-crown-5 ether), having five donor ‘oxygen’ atoms. The organic salts used for complexation were salts of nitrophenols. Products were isolated from silver salts of all the three nitrophenols, 2-nitrophenol (ONPH), 2, 4-dinitrophenol (DNPH) and 2, 4, 6-trinitrophenol (TNPH), having general formula of [Ag. L](Pic-), where L = 15C5 and Pic-= Picrate anion. The bonding pattern and structure of complexes were suggested from elemental analysis, molar conductivity, UV-Vis, IR, and 1H-NMR spectral analysis.
