Redetermination of the crystal structure of caesium tetra-fluorido-bromate(III) from single-crystal X-ray diffraction data.

ABSTRACT: Caesium tetra-fluorido-bromate(III), CsBrF₄, was crystallized in form of small blocks by melting and recrystallization. The crystal structure of CsBrF₄ was redetermined from single-crystal X-ray diffraction data. In comparison with a previous study based on powder X-ray diffraction data [Ivlev et al. (2013 ▸). Z. Anorg. Allg. Chem. 639, 2846-2850], bond lengths and angles were determined with higher precision, and all atoms were refined with anisotropic displacement parameters. It was confirmed that the structure of CsBrF₄ contains two square-planar [BrF₄]^- anions each with point group symmetry mmm, and a caesium cation (site symmetry mm2) that is coordinated by twelve fluorine atoms, forming an anti-
