BaB2F8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Ba–F bond distances ranging from 2.69–3.13 Å. In the second Ba2+ site, Ba2+ is bonded in a 9-coordinate geometry to nine F1- atoms. There are a spread of Ba–F bond distances ranging from 2.68–3.12 Å. There are four inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of B–F bond distances ranging from 1.41–1.43 Å. In the second B3+ site, B3+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of B–F bond distances ranging from 1.40–1.45 Å. In the third B3+ site, B3+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of B–F bond distances ranging from 1.40–1.45 Å.
