revealed reversible uncomplicated oxidations, whereas the cyclic voltammogram of the ruthenocenyl derivative 5c showed an irreversible oxidation. Compounds 2c–5c were tested for their antiproliferative activity against human MCF-7 breast adenocarcinoma and HT-29 colon carcinoma cells. Compounds 3c–5c were moderately active against MCF-7 cancerous cells. Atomic absorption spectroscopy measurements on compound
