Abstract

The crystal structure of Rb3NbO8 (SG I4̅2m, Nr. 121) has been determined on single crystals to a final R = 0.041. The structure is isotypic to the K3CrO8 type. Vibrational spectra of the title compound have been recorded on powdered samples and are discussed with respect to the internal vibrations of the peroxo-group and the dodecahedral NbO83- ion. The stretching vibrations of the O22- groups are found at 838 (Raman) and 813 cm- 1(IR). A factor group analysis for the K3CrO8 type is given.
