A novel germanium‐containing copolymer 3 a having a germanium(IV) unit and a trimethylene sulfide unit alternatingly in the main chain was prepared by the combined use of a germylene, 1,3‐bis(trimethylsilyl)‐1,3‐diaza‐2‐germa(II)‐indan ( 1 a ) and thietane ( 2 ). The resulting copolymer has a very high molecular weight (M̄ w > 10 6 ). The usage of a germylene, bis[bis(trimethylsilyl)aminato]germanium(II) ( 1 b ), as a comonomer also gave an alternating copolymer 3 b with high molecular weight in good yields. On the other hand, the reaction of a germylene, bis( N ‐trimethylsilyl‐ tert ‐butylaminato)germanium(II) ( c ), with thietane afforded a 1 : 1 adduct 4c having a 1‐thia‐2‐germacyclopentane structure without producing an alternating copolymer.
