Investigation of the CO releasing ability of azachalcone bound Mn(I) tricarbonyl complexes and their antiproliferative properties

Abstract

A series of [Mn(CO)3(L)Br] complexes (1–5) are synthesized using azachalcones as ligands, wherein they are coordinated to the manganese metal through the nitrogen and oxygen donor atoms. Their characterization using various spectroscopic techniques, stability analysis in dimethyl sulfoxide solvent, photodecomposition analysis, and antiproliferative effect are reported herein. These complexes release CO upon exposure to green light radiation. DFT and TD-DFT investigations are also reported to gather information regarding the electronic features of these complexes.
