The material described by SmRe3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Sm(1) is bonded in a distorted body-centered cubic geometry to six equivalent Re(2) and eight equivalent Re(1) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to four equivalent Sm(1) and four equivalent Re(2) atoms to form a mixture of distorted edge, corner, and face-sharing ReSm4Re4 tetrahedra. In the second Re site, Re(2) is bonded in a 14-coordinate geometry to six equivalent Sm(1) and eight equivalent Re(1) atoms. is represented by the CIF card [CIF]
