SrBrCl is half-Heusler structured and crystallizes in the cubic F-43m space group. Sr(1) is bonded to six equivalent Br(1) and four equivalent Cl(1) atoms to form a mixture of distorted corner and face-sharing SrBr6Cl4 tetrahedra. Br(1) is bonded to six equivalent Sr(1) atoms to form BrSr6 octahedra that share corners with six equivalent Br(1)Sr6 octahedra, corners with twelve equivalent Cl(1)Sr4 tetrahedra, edges with twelve equivalent Br(1)Sr6 octahedra, and faces with four equivalent Cl(1)Sr4 tetrahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded to four equivalent Sr(1) atoms to form ClSr4 tetrahedra that share corners with twelve equivalent Br(1)Sr6 octahedra, corners with twelve equivalent Cl(1)Sr4 tetrahedra, and faces with four equivalent Br(1)Sr6 octahedra. The corner-sharing octahedral tilt angles are 55°.
