Pd(II) complexes of aliphatic polyamine ligands in aqueous solution: Thermodynamic and structural features

This review collects the stability constants of Pd(II) complexes with amine s determined in aqueous solution. The 23 ligands considered herein, span am monia to acyclic and macrocyclic polyamines. Also the few enthalpy and entr opy changes available for such complexation reactions are reported. The the rmodynamic data are discussed, taking into account the structural informati on given for these complexes by spectroscopic measurements (UV-vis, NMR) in solution and X-ray analyses in the solid state. The effects due to nitroge n alkylation of the ligands, as well as the characteristics determined by t he ligand structures (acyclic, macrocyclic) are considered. (C) 1999 Elsevi er Science S.A.
