The structure described by Na2Yb2B2TeO10 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded in a 8-coordinate geometry to one O(2), one O(4), two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms. Yb(1) is bonded to one O(1), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form distorted YbO7 pentagonal bipyramids that share corners with two equivalent Te(1)O6 octahedra,  an edgeedge with one Te(1)O6 octahedra, and edges with three equivalent Yb(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles range from 47-49°. B(1) is bonded in a trigonal planar geometry to one O(1), one O(3), and one O(4) atom.

There are five inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent Na(1), one Yb(1), and one B(1) atom.

In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Na(1), one B(1), and one Te(1) atom. In the fourth O site, O(4) is bonded to one Na(1), two equivalent Yb(1), and one B(1) atom to form distorted ONaYb2B tetrahedra that share corners with three equivalent O(2)NaYb2Te tetrahedra,  an edgeedge with one O(4)NaYb2B tetrahedra, and  an edgeedge with one O(2)NaYb2Te tetrahedra.
