BaSrEuWO6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted q6 geometry to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. Sr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SrO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-29°. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Eu site, Eu(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(3) atoms. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-29°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Sr(1), one Eu(1), and one W(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ba(1), one Sr(1), one Eu(1), and one W(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Sr(1), one Eu(2), and one W(1) atom.
