Synthesis and characteristics of four new copper(II) carboxylate complexes with adamantane fragment

Abstract

The paper considers the results of synthesis, elemental analysis, and spectroscopic methods (IR, UV-vis) of four new copper(II) complexes with anions of 1-adamantanecarboxylic acid, 4-(1-adamantyl)benzoic acid and their L-valine derivatives as ligands. Based on the obtained spectral data, the authors assumed the biyaderic structure of these complexes with bidentate coordination of carboxylate ligands of the type [Cu2+2(RCOO-)4(H2O)2], with RCOO-as carboxylate ligands. The synthesised compounds are of interest as low toxic potential therapeutic agents with anti-inflammatory and anti-cancer activity.
