An adamantane-shaped, ferrocenyl-substituted tin selenide complex, [(FcSn)(4)Se-6] (1; Fc = ferrocenyl), and a ferrocenyl-substituted tin telluride five-membered ring, [(Fc(2)Sn)(3)Te-2] (2), were obtained upon treatment of FcSnCl(3) with K2E (E = Se, Te). Complex 1 further reacts with Na2S 9H(2)O and [Cu(PPh3)(3)Cl] to form a ternary complex, [(CuPPh3)(6)(S/Se)(6)(SnFc)(2)] (3). We discuss structures, optical and electrochemical properties as well as Mossbauer spectra.
