The new compounds K 4 Nb 2 S 10 O and Rb 4 Nb 2 S 10 O have been synthesized by the reaction of potassium or rubidium alkaline polychalcogenides with NbO 2 , Nb 2 O 5 , or mixtures of Nb and NbO. Their structures consist of discrete [Nb 2 Q 11 ] 4– anions (Q = O, S) built up of two face‐sharing pentagonal bipyramids, which are connected via the alkali metal cations.
