Synthesis and reactivity of ferrocenyl functionalized Sn/S cages

摘要

Depending on the solvent used, the mono-stannylated FcSnCl_3, (1) reacts with Na_2S to give ionic [Na_6(Me_2CO)_4(OH_2)6] [(FcSn)_3S_6]2 (2), with a yet unprecedented thiostannate anion, or the adamantane-type Sn/S-cluster [(FcSn)_4S_6] (3). Complex 2 reacts readily with [Ni(acac)_2], yielding the mixed-metallic complex [{Na(thf)_(3.5)}_2{(FcSn)_8Ni_3S_(16)}]·2THF (4·2THF); the structures of 1-4 are discussed as well as Mossbauer spectra.
