Trirubidium Tetrathioniobate

The reaction of Rb₂S₃, NbO and S yields single crystals of trirubidium tetrathioniobate, Rb₃NbS₄. The crystal structure is based on discrete tetrahedral NbS₄ anions, which are connected via Rb cations. The compound crystallizes with the K₃VS₄ structure type and is isotypic with previously reported K and Cs analogues.
