Abstract
AbstractCs3AsGeSe5 and Cs4Ge2Se6 can be prepared by methanolothermal reaction of elemental As, Ge and Se with Cs2CO3 at 190 °C. The former quaternary phase contains zweier $^{1}_{\infty}$[{AsGeSe5}3−] chains consisting of corner‐bridged GeSe4 tetrahedra and AsSe3 pyramids and represents the first GeIV‐AsIII chalcogenidometalate. Cs4Ge2Se6 exhibits discrete [Ge2Se6]4− anions formed by two edge‐sharing GeSe4 tetrahedra.
