The material structure described by SrSc2O4 crystallizes in the orthorhombic Cmcm space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. Sc(1) is bonded to one O(3), two equivalent O(1), and three equivalent O(2) atoms to form a mixture of corner and edge-sharing ScO6 octahedra. The corner-sharing octahedral tilt angles range from 0-42°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1) and four equivalent Sc(1) atoms to form distorted OSr2Sc4 octahedra that share corners with two equivalent O(1)Sr2Sc4 octahedra, corners with eight equivalent O(2)Sr2Sc3 trigonal bipyramids, edges with two equivalent O(1)Sr2Sc4 octahedra, edges with four equivalent O(3)Sr2Sc2 tetrahedra, and edges with six equivalent O(2)Sr2Sc3 trigonal bipyramids. The corner-sharing octahedral tilt angles are 47°. In the second O site, O(2) is bonded to two equivalent Sr(1) and three equivalent Sc(1) atoms to form distorted OSr2Sc3 trigonal bipyramids that share corners with four equivalent O(1)Sr2Sc4 octahedra, corners with five equivalent O(3)Sr2Sc2 tetrahedra, corners with two equivalent O(2)Sr2Sc3 trigonal bipyramids, edges with three equivalent O(1)Sr2Sc4 octahedra,  an edgeedge with one O(3)Sr2Sc2 tetrahedra, and edges with five equivalent O(2)Sr2Sc3 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 10-41°. In the third O site, O(3) is bonded to two equivalent Sr(1) and two equivalent Sc(1) atoms to form distorted OSr2Sc2 tetrahedra that share corners with two equivalent O(3)Sr2Sc2 tetrahedra, corners with ten equivalent O(2)Sr2Sc3 trigonal bipyramids, edges with four equivalent O(1)Sr2Sc4 octahedra, and edges with two equivalent O(2)Sr2Sc3 trigonal bipyramids. is represented by the CIF card [CIF]
