The compound described by SrBiO2Br is lead oxide-derived structured and crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and four equivalent Br(1) atoms. Bi(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. O(1) is bonded to two equivalent Sr(1) and two equivalent Bi(1) atoms to form OSr2Bi2 tetrahedra that share corners with four equivalent O(1)Sr2Bi2 tetrahedra, corners with eight equivalent Br(1)Sr4 tetrahedra, and edges with four equivalent O(1)Sr2Bi2 tetrahedra. Br(1) is bonded to four equivalent Sr(1) atoms to form BrSr4 tetrahedra that share corners with four equivalent Br(1)Sr4 tetrahedra, corners with sixteen equivalent O(1)Sr2Bi2 tetrahedra, and edges with four equivalent Br(1)Sr4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
