Synthesis and Determination of Stability Constants of a New Coumarin Derivative with some Transition Metal Ions in Acetonitrile
Journal Title: Journal of Biomedical and Pharmaceutical Research - Year 2013, Vol 2, Issue 2
Abstract
In this work, the synthesis and complexation properties of a new compound, towards certain transition metal ions, (M, where M = Ni, cd, Ag, Zn, Cu) in acetonitrile has been reported. The stoichiometries of complexes were determined using UV- Visible spectroscopy data. The stability constants of complexes were influenced by parameters such as the type of metal, Ligand, counter ion or solvent. In this work the formation constants of the complexes were determined for the synthesized ligand with several metallic cations, in acetonitrile solution by UV - Visible spectrometry.
