Sr2VO4Br crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), four equivalent O(2), and two equivalent Br(1) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent O(2), four equivalent O(1), and two equivalent Br(1) atoms. V(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Sr(1), two equivalent Sr(2), and one V(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Sr(2), two equivalent Sr(1), and one V(1) atom. Br(1) is bonded in a see-saw-like geometry to two equivalent Sr(1) and two equivalent Sr(2) atoms.
