Yb(NdS2)2 crystallizes in the orthorhombic C222_1 space group. Yb(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent S(1) and two equivalent S(2) atoms. Nd(1) is bonded to two equivalent S(1) and three equivalent S(2) atoms to form distorted edge-sharing NdS5 square pyramids. There are two inequivalent S sites. In the first S site, S(2) is bonded in a rectangular see-saw-like geometry to one Yb(1) and three equivalent Nd(1) atoms. In the second S site, S(1) is bonded in a 3-coordinate geometry to one Yb(1) and two equivalent Nd(1) atoms.
Yb(NdS2)2 crystallizes in the orthorhombic C222_1 space group. Yb(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent S(1) and two equivalent S(2) atoms. Both Yb(1)-S(1) bond lengths are 2.68 Å. Both Yb(1)-S(2) bond lengths are 2.75 Å. Nd(1) is bonded to two equivalent S(1) and three equivalent S(2) atoms to form distorted edge-sharing NdS5 square pyramids. There is one shorter (2.71 Å) and one longer (2.74 Å) Nd(1)-S(1) bond length. There are a spread of Nd(1)-S(2) bond distances ranging from 2.78-2.95 Å. There are two inequivalent S sites. In the first S site, S(2) is bonded in a rectangular see-saw-like geometry to one Yb(1) and three equivalent Nd(1) atoms. In the second S site, S(1) is bonded in a 3-coordinate geometry to one Yb(1) and two equivalent Nd(1) atoms.
