The compound described by K3Na is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a body-centered cubic geometry to four equivalent K(2) and four equivalent Na(1) atoms. In the second K site, K(2) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. Na(1) is bonded in a body-centered cubic geometry to eight equivalent K(1) atoms. is represented by the CIF card [CIF]
