The crystal structure described by BaMg2Hf crystallizes in the cubic F-43m space group. Ba(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mg(2), six equivalent Mg(1), and four equivalent Hf(1) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 14-coordinate geometry to six equivalent Ba(1), four equivalent Mg(2), and four equivalent Hf(1) atoms. In the second Mg site, Mg(2) is bonded in a distorted body-centered cubic geometry to four equivalent Ba(1) and four equivalent Mg(1) atoms. Hf(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ba(1) and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
