Stereospecific ligands and their complexes. Part XV. Synthesis, characterization and cytotoxicity of novel platinum(IV) complexes with some esters of ethylenediamine-N,,N'N′-di-S,,S-(2,2′'-dibenzyl)acetic acid. Crystal structure of O,,O′'-dipropyl-e

The complexes have been obtained by direct reaction of potassium-hexachloridoplatinate(IV) with corresponding esters of ethylenediamine-N,,N′'-di-S,,S-(2,2′'-dibenzyl)acetic acid.
