The material structure described by YbV4O8 crystallizes in the triclinic P-1 space group. Yb(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), two equivalent O(4), two equivalent O(6), and two equivalent O(8) atoms. There are four inequivalent V sites. In the first V site, V(1) is bonded to one O(2), two equivalent O(4), and three equivalent O(5) atoms to form a mixture of edge and corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 53-56°. In the second V site, V(2) is bonded to one O(1), two equivalent O(3), and three equivalent O(6) atoms to form a mixture of edge and corner-sharing VO6 octahedra.
