In the Sm8Al7F40 framework, there are eight inequivalent Sm2+ sites. In the first Sm2+ site, Sm2+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Sm–F bond distances ranging from 2.33–2.54 Å. In the second Sm2+ site, Sm2+ is bonded in a 8-coordinate geometry to eight F1- atoms. There are a spread of Sm–F bond distances ranging from 2.22–2.67 Å. In the third Sm2+ site, Sm2+ is bonded in a 5-coordinate geometry to five F1- atoms.
