The material described by Yb2VO5 crystallizes in the monoclinic C2/c space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 7-coordinate geometry to one O(1), one O(3), one O(4), two equivalent O(2), and two equivalent O(5) atoms. In the second Yb site, Yb(2) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. V(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(3) is bonded to one Yb(1), two equivalent Yb(2), and one V(1) atom to form distorted OYb3V tetrahedra that share corners with two equivalent O(5)Yb4 trigonal pyramids,  an edgeedge with one O(3)Yb3V tetrahedra, and edges with two equivalent O(5)Yb4 trigonal pyramids. In the second O site, O(4) is bonded in a 4-coordinate geometry to one Yb(1), two equivalent Yb(2), and one V(1) atom. In the third O site, O(5) is bonded to two equivalent Yb(1) and two equivalent Yb(2) atoms to form OYb4 trigonal pyramids that share corners with two equivalent O(3)Yb3V tetrahedra, edges with two equivalent O(3)Yb3V tetrahedra, and edges with two equivalent O(5)Yb4 trigonal pyramids. In the fourth O site, O(1) is bonded in a 3-coordinate geometry to one Yb(1), one Yb(2), and one V(1) atom. In the fifth O site, O(2) is bonded in a 3-coordinate geometry to one Yb(2), two equivalent Yb(1), and one V(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
