Y2VO5 crystallizes in the monoclinic C2/c space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(5) atoms to form distorted YO6 octahedra that share corners with four equivalent V(1)O4 tetrahedra and edges with two equivalent Y(1)O6 octahedra. In the second Y site, Y(2) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share corners with four equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-70°. There are five inequivalent O sites. In the first O site, O(3) is bonded in a 4-coordinate geometry to one Y(1), two equivalent Y(2), and one V(1) atom. In the second O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Y(2) and one V(1) atom. In the third O site, O(5) is bonded to two equivalent Y(1) and two equivalent Y(2) atoms to form edge-sharing OY4 tetrahedra. In the fourth O site, O(1) is bonded in a 3-coordinate geometry to one Y(1), one Y(2), and one V(1) atom. In the fifth O site, O(2) is bonded in a trigonal non-coplanar geometry to two equivalent Y(1) and one V(1) atom.
