A Germanium Sesquisulfide, (<i>t</i>BuGe)₄S₆, without Adamantane Structure

Abstract

Two sulfur-bridged, almost planar Ge2S2, four-membered rings are found in the novel sesquichalcogenide 1, which is formed from the reaction of tBuGeCl3 with (NH4)2S5. Due to thermal strain, 1, rearranges to the known (tBuGe)4S6 isomer with an adamantane framework. If this second compound is prepared directly from tBuGeCl3 and H2S/pyridine, bisgermanium thiolates are detected as intermediates.
