Yb2WN2O3 crystallizes in the tetragonal I-4m2 space group. Yb(1) is bonded in a 6-coordinate geometry to two equivalent N(1), two equivalent O(1), and two equivalent O(2) atoms. W(1) is bonded in a body-centered cubic geometry to four equivalent N(1) and four equivalent O(2) atoms. N(1) is bonded to two equivalent Yb(1) and two equivalent W(1) atoms to form NYb2W2 tetrahedra that share corners with two equivalent O(2)Yb2W2 tetrahedra, corners with four equivalent O(1)Yb4 tetrahedra, corners with eight equivalent N(1)Yb2W2 tetrahedra, and edges with five equivalent O(2)Yb2W2 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Yb(1) atoms to form OYb4 tetrahedra that share corners with four equivalent O(2)Yb2W2 tetrahedra, corners with four equivalent O(1)Yb4 tetrahedra, corners with eight equivalent N(1)Yb2W2 tetrahedra, and edges with two equivalent O(2)Yb2W2 tetrahedra. In the second O site, O(2) is bonded to two equivalent Yb(1) and two equivalent W(1) atoms to form OYb2W2 tetrahedra that share corners with two equivalent N(1)Yb2W2 tetrahedra, corners with two equivalent O(1)Yb4 tetrahedra, corners with eight equivalent O(2)Yb2W2 tetrahedra,  an edgeedge with one O(1)Yb4 tetrahedra, and edges with five equivalent N(1)Yb2W2 tetrahedra.
