NaAc3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a body-centered cubic geometry to six equivalent Ac(2) and eight equivalent Ac(1) atoms. There are two inequivalent Ac sites. In the first Ac site, Ac(1) is bonded in a distorted body-centered cubic geometry to four equivalent Na(1) and four equivalent Ac(2) atoms. In the second Ac site, Ac(2) is bonded in a distorted body-centered cubic geometry to six equivalent Na(1) and eight equivalent Ac(1) atoms.
