In the fourth V site, V(4) is bonded to one O(3), one O(6), one O(7), and one O(8) atom to form corner-sharing VO4 tetrahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(2) and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Yb(1), one V(2), and one V(3) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Yb(1), one V(3), and one V(4) atom. In the fourth O site, O(4) is bonded to one Yb(1), one V(3), and two equivalent V(2) atoms to form OYbV3 tetrahedra that share corners with two equivalent O(4)YbV3 tetrahedra, corners with two equivalent O(6)Yb2V3 trigonal bipyramids, and  an edgeedge with one O(6)Yb2V3 trigonal bipyramid. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Yb(1), one V(1), and one V(2) atom. In the sixth O site, O(6) is bonded to two equivalent Yb(1), one V(4), and two equivalent V(3) atoms to form distorted OYb2V3 trigonal bipyramids that share corners with two equivalent O(4)YbV3 tetrahedra,  an edgeedge with one O(4)YbV3 tetrahedra, and edges with two equivalent O(6)Yb2V3 trigonal bipyramids. In the seventh O site, O(7) is bonded in a distorted T-shaped geometry to one Yb(1), one V(1), and one V(4) atom.
