SrHfRe2 crystallizes in the cubic F-43m space group. Sr(1) is bonded in a distorted body-centered cubic geometry to four equivalent Hf(1), four equivalent Re(1), and six equivalent Re(2) atoms. Hf(1) is bonded in a distorted body-centered cubic geometry to four equivalent Sr(1) and four equivalent Re(2) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to four equivalent Sr(1) and four equivalent Re(2) atoms to form distorted ReSr4Re4 tetrahedra that share corners with twelve equivalent Re(2)Sr6Hf4Re4 tetrahedra, edges with twelve equivalent Re(1)Sr4Re4 tetrahedra, and faces with four equivalent Re(2)Sr6Hf4Re4 tetrahedra. In the second Re site, Re(2) is bonded to six equivalent Sr(1), four equivalent Hf(1), and four equivalent Re(1) atoms to form distorted ReSr6Hf4Re4 tetrahedra that share corners with six equivalent Re(2)Sr6Hf4Re4 tetrahedra, corners with twelve equivalent Re(1)Sr4Re4 tetrahedra, faces with four equivalent Re(1)Sr4Re4 tetrahedra, and faces with twelve equivalent Re(2)Sr6Hf4Re4 tetrahedra.
