The incorporation of Sb atoms into sulfido germanate and sulfido stannate frameworks, which is reflected by notable narrowing of the optical band gaps of the solid compounds, was realized by ionothermal treatment, and thus reconstruction, of potassium salts of [SnS 4 ] 4− or [Ge 4 S 10 ] 4− anions with SbCl 3 in imidazolium‐based ionic liquids. The image illustrates the highly symmetrical arrangement of one [GeS 4 ] 4− unit and six [Ge 2 Sb 2 S 7 ] 2− units in the anionic substructure of one of the title compounds.
