The RbSbGe₃O₉ compound, grown by the high-temperature solution technique from the Rb₂Mo₄O₁₃ flux, crystallizes in the trigonal non-centrosymmetric space group P31c (n^o. 159). The structure was solved and refined from single-crystal X-ray diffraction data recorded at ambient temperature. The unit cell contains six formula units. The three-dimensional RbSbGe₃O₉ network is built with three-membered units [Ge₃O₉]^6- of regular germanate tetrahedra involving three crystallographically independent Ge atoms. The Ge₃O₃ central rings located in the ab plane deviate only slightly from the planarity. Antimony Sb^V is octahedrally coordinated by oxygen, and rubidium (Rb⁺), which is surrounded by six oxygen atoms, is located in the channels of the 3-D network. The structure of RbSbGe₃O₉ containing both isolated SbO₆ octahedra and Ge₃O₉ cyclic units is comparable but not isostructural to the benitoite type. The almost flat character of the Ge₃O₃ rings is also attested by the vibrational study at room temperature via non-polarized infrared and Raman spectroscopy.
