Synthesis and spectroscopic characterization of polynuclear silver(I) complex with 2,2'-biquinoline

Abstract

Polynuclear silver(I) complex, [Ag(NO3-O)(2,2’-bq-N,N’)]n, was synthesized by the reaction of equimolar amount of silver(I) nitrate and 2,2’-biquinoline (2,2’-bq) in ethanol at room temperature. The characterization of the complex was established on the basis of elemental microanalysis, IR, NMR (H and C) and UV-Vis spectroscopic techniques. The results of spectroscopic analyses revealed that in [Ag(NO3-O)(2,2’-bq-N,N’)]n complex, 2,2’-bq ligand behaves as a chelate, while the remaining coordination sites are occupied by the oxygen atoms of two nitrates.
