Novel germanium-containing cyclic polysulfides 1,2,3,4,5-tetrathiagermolanes 5 (Tbt(Ar)-GeS₄; Tbt = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl; Ar = mesityl, 2,6-diethylphenyl, 2,4,6-triisopropylphenyl) have been synthesized, and the molecular structure of Tbt(Mes)GeS₄ was determined by X-ray crystallographic analysis. Reaction of the tetrathiagermolanes 5 with diphenyldiazomethane gave 1,2,3,5-tetrathia-4-germacyclohexanes 10, 1,2,4,5-tetrathia-3-germacyclohexanes 11, and 1,2,4-trithia-3-germacyclopentanes 12. The structure of 1,2,3,5-tetrathia-4-germacyclohexane 10a was determined by X-ray structural analysis.
