The material structure described by Yb3NdS6 crystallizes in the monoclinic P2_1/m space group. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 6-coordinate geometry to one S(2), two equivalent S(6), and three equivalent S(1) atoms. In the second Yb site, Yb(2) is bonded to one S(1), two equivalent S(5), and three equivalent S(3) atoms to form YbS6 octahedra that share corners with three equivalent Yb(3)S5 square pyramids and edges with four equivalent Yb(2)S6 octahedra.

The corner-sharing octahedral tilt angles range from 55-71°. Nd(1) is bonded in a 8-coordinate geometry to one S(2), two equivalent S(4), two equivalent S(5), and three equivalent S(6) atoms.

In the fifth S site, S(5) is bonded in a 5-coordinate geometry to two equivalent Yb(2), two equivalent Nd(1), and one S(4) atom.
