The crystal structure described by ScV(SeO4)2 crystallizes in the monoclinic P2_1/c space group. Sc(1) is bonded to one O(2), one O(5), one O(6), two equivalent O(7), and two equivalent O(8) atoms to form distorted edge-sharing ScO7 pentagonal bipyramids. V(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), and two equivalent O(1) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(5), and one O(6) atom. In the second Se site, Se(2) is bonded in a distorted trigonal non-coplanar geometry to one O(4), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a bent 150 degrees geometry to one Sc(1) and one Se(1) atom. In the second O site, O(6) is bonded in a bent 150 degrees geometry to one Sc(1) and one Se(1) atom. In the third O site, O(7) is bonded in a 3-coordinate geometry to two equivalent Sc(1) and one Se(2) atom. In the fourth O site, O(8) is bonded in a distorted trigonal planar geometry to two equivalent Sc(1) and one Se(2) atom. In the fifth O site, O(1) is bonded in a trigonal planar geometry to two equivalent V(1) and one Se(1) atom. In the sixth O site, O(2) is bonded in a bent 120 degrees geometry to one Sc(1) and one V(1) atom. In the seventh O site, O(3) is bonded in a single-bond geometry to one V(1) atom. In the eighth O site, O(4) is bonded in a bent 120 degrees geometry to one V(1) and one Se(2) atom. is represented by the CIF file [CIF]
