Dibromido[(S,S)-ethylenediamine-N,N′-di-2-(3-cyclohexyl)propanoato]platinum(IV): synthesis, characterization, and DFT calculations

Abstract

Bromido complex of platinum(IV) with (S,S)-ethylenediamine-N,N′-di-2-(3-cyclohexyl)propanoic acid was synthesized. The reaction was performed in water solution in the presence of lithium hydroxide. In this reaction system, (S,S)-ethylenediamine-N,N′-di-2-(3-cyclohexyl)propanoic acid exists as the dicarboxylato anion and coordinates as a tetradentate ONNO ligand. The complex was characterized by ¹H and ¹³C NMR, IR and UV-Vis spectroscopy. The sym-cis configuration has been elucidated using DFT calculations.
