Nd2SnS5 crystallizes in the orthorhombic Pbam space group. Nd(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(3), and four equivalent S(2) atoms. Sn(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form edge-sharing SnS6 octahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Nd(1) and two equivalent Sn(1) atoms. In the second S site, S(2) is bonded to four equivalent Nd(1) and one Sn(1) atom to form a mixture of distorted corner and edge-sharing SNd4Sn trigonal bipyramids. In the third S site, S(3) is bonded in a square co-planar geometry to four equivalent Nd(1) atoms.
Nd2SnS5 crystallizes in the orthorhombic Pbam space group. Nd(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(3), and four equivalent S(2) atoms. There is one shorter (2.96 Å) and one longer (3.10 Å) Nd(1)-S(1) bond length. Both Nd(1)-S(3) bond lengths are 2.80 Å. There are two shorter (2.98 Å) and two longer (3.03 Å) Nd(1)-S(2) bond lengths. Sn(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form edge-sharing SnS6 octahedra. Both Sn(1)-S(2) bond lengths are 2.58 Å. All Sn(1)-S(1) bond lengths are 2.59 Å. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Nd(1) and two equivalent Sn(1) atoms.
