The material structure described by Bi2VO5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(7), two equivalent O(4), and two equivalent O(5) atoms to form distorted corner-sharing VO5 square pyramids. In the second V site, V(2) is bonded in a 5-coordinate geometry to one O(6) and four equivalent O(4) atoms. There are four inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Bi site, Bi(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. In the third Bi site, Bi(3) is bonded in a 6-coordinate geometry to two equivalent O(7) and four equivalent O(1) atoms. In the fourth Bi site, Bi(4) is bonded in a body-centered cubic geometry to four equivalent O(2) and four equivalent O(4) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Bi(2) and two equivalent Bi(3) atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra. In the second O site, O(2) is bonded to two equivalent Bi(1) and two equivalent Bi(4) atoms to form OBi4 tetrahedra that share corners with two equivalent O(2)Bi4 tetrahedra, corners with two equivalent O(3)Bi4 tetrahedra, corners with eight equivalent O(4)V2Bi2 tetrahedra,  an edgeedge with one O(3)Bi4 tetrahedra, edges with two equivalent O(4)V2Bi2 tetrahedra, and edges with three equivalent O(2)Bi4 tetrahedra. In the third O site, O(3) is bonded to two equivalent Bi(1) and two equivalent Bi(2) atoms to form OBi4 tetrahedra that share corners with two equivalent O(1)Bi4 tetrahedra, corners with two equivalent O(2)Bi4 tetrahedra, corners with four equivalent O(4)V2Bi2 tetrahedra,  an edgeedge with one O(1)Bi4 tetrahedra,  an edgeedge with one O(2)Bi4 tetrahedra, and edges with two equivalent O(3)Bi4 tetrahedra.
