KMg3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded in a distorted body-centered cubic geometry to six equivalent Mg(2) and eight equivalent Mg(1) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted body-centered cubic geometry to four equivalent K(1) and four equivalent Mg(2) atoms. In the second Mg site, Mg(2) is bonded in a 14-coordinate geometry to six equivalent K(1) and eight equivalent Mg(1) atoms.
