N2 - The new thioaluminogermanate Na(AlS2)(GeS2)4 (1) was successfully synthesized by a direct combination reaction. The compound crystallizes in the monoclinic space group P21/n (no. 14) with unit cell parameters a = 6.803(3) Å, b = 38.207(2) Å, c = 6.947(4) Å, and β = 119.17(3)°. The crystal structure is composed of a [(AlS2)(GeS2)4]− 3D polyanionic network, in which Al and Ge atoms share the atomic positions and Na cations occupy the channels and voids formed by the connection of (Ge/Al)S4 tetrahedra. The title compound shows a cation-exchange property with monovalent Ag+ and Cu+ ions at room temperature in solvent media, resulting in the formation of the isostructural compounds Ag(AlS2)(GeS2)4 (2) and Cu(AlS2)(GeS2)4 (3), respectively. The ion-exchange products Ag(AlS2)(GeS2)4 (2) and Cu(AlS2)(GeS2)4 (3) show higher air stability and narrower bandgap energies compared to those of the parent compound Na(AlS2)(GeS2)4 (1).
