ABSTRACT:
Macrocyclic crown ethers are excellent hosts for metal ions and are now often used for the determination of alkali, alkaline earth and transition elements. Crown ethers have a significant coordination power towards silver ion. The present paper describes synthesis and characterization of some new Ag(I) complexes with 1,4,7,10,13,16,-hexaoxacyclooctadecane (18-crown-6 ether) and 2,3,11,12-dibenzo-1,4,7,10,13,16,-hexaoxacyclooctadeca-2,11-diene (dibenzo18-crown-6 ether), having six 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, 2,4-dinitrophenol and 2,4,6-trinitrophenol, having general formula of [Ag. L] (Pic-), where L = 18C6/db18C6 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.
