Synthesis and characterization of mixed ligand complexes of zinc(ll) with cytidine and amino acids^†

Abstract

Mixed ligand complexes of Zn(II) with cytidine and amino acids, <img src='http://www.niscair.res.in/jinfo/small.gif' border=0>-alanine, <img src='http://www.niscair.res.in/jinfo/small.gif' border=0>-phenylalanine and <img src='http://www.niscair.res.in/jinfo/small.gif' border=0>-tryptophan have been synthesized and characterized by elemental analysis, conductivity data, electronic spectra, IR, ¹H NMR and ¹³C NMR spectra. In these complexes, the nucleoside acts as a monodentate ligand involving only N(3) in metal coordination whereas the amino acids coordinate through carboxylate oxygen and amino nitrogen. The results drawn about binding sites of these octahedral complexes are compared with the results obtained from solution studies.
