The structure described by YbV4O8 crystallizes in the monoclinic Pc space group. Yb(1) is bonded in a distorted pentagonal planar geometry to one O(2), one O(3), one O(4), one O(7), and one O(8) atom. There are four inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), one O(4), and one O(8) atom to form VO4 tetrahedra that share  a cornercorner with one V(2)O4 tetrahedra and corners with three equivalent V(3)O5 trigonal bipyramids. In the second V site, V(2) is bonded to one O(1), one O(3), one O(5), and one O(6) atom to form VO4 tetrahedra that share  a cornercorner with one V(1)O4 tetrahedra,  a cornercorner with one V(3)O5 trigonal bipyramid, and  an edgeedge with one V(3)O5 trigonal bipyramid. In the third V site, V(3) is bonded to one O(1), one O(3), one O(4), one O(6), and one O(8) atom to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. In the fourth V site, V(4) is bonded in a trigonal planar geometry to one O(5), one O(6), and one O(7) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one V(2) and one V(3) atom. In the second O site, O(2) is bonded in a water-like geometry to one Yb(1) and one V(1) atom. In the third O site, O(3) is bonded in a distorted tetrahedral geometry to one Yb(1), one V(1), one V(2), and one V(3) atom. In the fourth O site, O(4) is bonded in a T-shaped geometry to one Yb(1), one V(1), and one V(3) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(2) and one V(4) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one V(2), one V(3), and one V(4) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one Yb(1) and one V(4) atom. In the eighth O site, O(8) is bonded in a distorted T-shaped geometry to one Yb(1), one V(1), and one V(3) atom. is represented by the CIF card [CIF]
