Depending on the ester alkyl group, the reaction of O,O-dialkylethylenediamine-N,N'-di-3-propanoate ligands (R(2)eddp) with potassium hexachloroplatinate(IV) afforded trans-dichloro(ethylenediamine-N,N'-di-3-propanoato)platinum(IV) and tetrachloro(O,O-dialkyl-ethylenediamine-N,N'-di-3-propanoato)platinum(IV) complexes. The complexes were characterized by elemental analysis, electronic absorption, infrared, H-1 and C-13 NMR spectroscopy. The trans configuration of [Pt(eddp)Cl-2] complex was confirmed by X-ray crystallography. (C) 2003 Elsevier B.V. All rights reserved.
