Single crystals of barium bis-[tetra-fluorido-bromate(III)], Ba[BrF4]2, were obtained in the form of tiny blocks. Crystal-structure refinement of Ba[BrF4]2 from single-crystal X-ray diffraction data confirmed the previous model obtained on the basis of powder data [Ivlev et al. (2014 ▸). Eur. J. Inorg. Chem. pp. 6261-6267], but with all atoms refined with anisotropic displacement parameters. The crystal structure consists of two symmetry-independent barium cations that are each coordinated by twelve fluorine atoms, forming edge-sharing polyhedra, and an almost square-planar [BrF4]- anion. The compound crystallizes in the Ba[AuF4]2 structure type.
Keywords: barium; crystal structure; re-refinement; tetrafluoridobromate(III).
