Ba2Sc2O5 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 7-coordinate geometry to one O(3), one O(4), two equivalent O(1), and three equivalent O(2) atoms. Sc(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing ScO4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Ba(1) and two equivalent Sc(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Ba(1) and one Sc(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Sc(1) atoms. In the fourth O site, O(4) is bonded in a distorted linear geometry to two equivalent Ba(1) and two equivalent Sc(1) atoms.
