Abstract
An adamantane-shaped, ferrocenyl-substituted
tin selenide complex, [(FcSn)<sub>4</sub>Se<sub>6</sub>] (<b>1</b>; Fc = ferrocenyl), and a ferrocenyl-substituted tin telluride five-membered
ring, [(Fc<sub>2</sub>Sn)<sub>3</sub>Te<sub>2</sub>] (<b>2</b>), were obtained upon treatment of FcSnCl<sub>3</sub> with K<sub>2</sub>E (E = Se, Te). Complex <b>1</b> further reacts with
Na<sub>2</sub>S·9H<sub>2</sub>O and [Cu(PPh<sub>3</sub>)<sub>3</sub>Cl] to form a ternary complex, [(CuPPh<sub>3</sub>)<sub>6</sub>(S/Se)<sub>6</sub>(SnFc)<sub>2</sub>] (<b>3</b>). We discuss
structures, optical and electrochemical properties as well as Mössbauer
spectra
