Li3Pr is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a body-centered cubic geometry to four equivalent Li(2) and four equivalent Pr(1) atoms. In the second Li site, Li(2) is bonded in a 14-coordinate geometry to eight equivalent Li(1) and six equivalent Pr(1) atoms. Pr(1) is bonded in a distorted body-centered cubic geometry to six equivalent Li(2) and eight equivalent Li(1) atoms.
