Abstract

Organometallic tin halides R2SnCl2 (R = {Cp(CO)2Fe}, {Cp(CO)3Mo}) react with Te(SiMe3)2 to form the compounds [{Cp(CO)2Fe}4Sn2Te2] 1, [{Cp(CO)3Mo}4Sn2Te2] 2 and [{Cp(CO)3Mo)4Sn4Te6] 3. According to crystal structure determinations, 1 and 2 contain planar Sn2Te2 rings. 3 consists of an adamantane-like Sn4Te6 framework.
