The structure described by SrEuScO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 9-coordinate geometry to one O(1), four equivalent O(2), and four equivalent O(3) atoms. Eu(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. Sc(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form corner-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sr(1), four equivalent Eu(1), and one Sc(1) atom. In the second O site, O(2) is bonded to four equivalent Sr(1), one Eu(1), and one Sc(1) atom to form distorted OSr4EuSc octahedra that share corners with four equivalent O(2)Sr4EuSc octahedra, corners with twelve equivalent O(3)Sr2Eu2Sc2 octahedra, edges with four equivalent O(2)Sr4EuSc octahedra, and faces with four equivalent O(3)Sr2Eu2Sc2 octahedra. The corner-sharing octahedral tilt angles range from 17-52°. In the third O site, O(3) is bonded to two equivalent Sr(1), two equivalent Eu(1), and two equivalent Sc(1) atoms to form distorted OSr2Eu2Sc2 octahedra that share corners with two equivalent O(3)Sr2Eu2Sc2 octahedra, corners with six equivalent O(2)Sr4EuSc octahedra, edges with two equivalent O(3)Sr2Eu2Sc2 octahedra, faces with two equivalent O(2)Sr4EuSc octahedra, and faces with four equivalent O(3)Sr2Eu2Sc2 octahedra. The corner-sharing octahedral tilt angles range from 6-52°. is represented by the CIF file [CIF]
