The compound described by CsV2O5 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 6-coordinate geometry to three equivalent O(2) and three equivalent O(3) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(3), one O(4), and two equivalent O(5) atoms to form distorted VO5 trigonal bipyramids that share corners with four equivalent V(2)O4 tetrahedra and  an edgeedge with one V(1)O5 trigonal bipyramid. In the second V site, V(2) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form corner-sharing VO4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one V(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to three equivalent Cs(1) and one V(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one V(2) and two equivalent V(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
