W2ReBr crystallizes in the cubic F-43m space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to four equivalent W(2), four equivalent Re(1), and six equivalent Br(1) atoms to form distorted WRe4W4Br6 tetrahedra that share corners with six equivalent W(1)Re4W4Br6 tetrahedra, corners with twelve equivalent W(2)W4Br4 tetrahedra, faces with four equivalent W(2)W4Br4 tetrahedra, and faces with twelve equivalent W(1)Re4W4Br6 tetrahedra. In the second W site, W(2) is bonded to four equivalent W(1) and four equivalent Br(1) atoms to form distorted WW4Br4 tetrahedra that share corners with twelve equivalent W(1)Re4W4Br6 tetrahedra, edges with twelve equivalent W(2)W4Br4 tetrahedra, and faces with four equivalent W(1)Re4W4Br6 tetrahedra. Re(1) is bonded in a distorted body-centered cubic geometry to four equivalent W(1) and four equivalent Br(1) atoms. Br(1) is bonded in a distorted body-centered cubic geometry to four equivalent W(2), six equivalent W(1), and four equivalent Re(1) atoms.
