KCa3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded in a body-centered cubic geometry to eight equivalent Ca(1) atoms. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a body-centered cubic geometry to four equivalent K(1) and four equivalent Ca(2) atoms. In the second Ca site, Ca(2) is bonded in a body-centered cubic geometry to eight equivalent Ca(1) atoms.
