The structure described by Sc2V2O7 crystallizes in the monoclinic C2/m space group. Sc(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted ScO6 pentagonal pyramids that share corners with four equivalent V(1)O5 trigonal bipyramids, edges with three equivalent Sc(1)O6 pentagonal pyramids, and edges with two equivalent V(1)O5 trigonal bipyramids. V(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted VO5 trigonal bipyramids that share corners with four equivalent Sc(1)O6 pentagonal pyramids,  a cornercorner with one V(1)O5 trigonal bipyramid, edges with two equivalent Sc(1)O6 pentagonal pyramids, and  an edgeedge with one V(1)O5 trigonal bipyramid. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Sc(1) and one V(1) atom. In the second O site, O(2) is bonded to two equivalent Sc(1) and two equivalent V(1) atoms to form edge-sharing OSc2V2 trigonal pyramids. In the third O site, O(3) is bonded in a linear geometry to two equivalent V(1) atoms. is represented by the CIF card [CIF]
