Nd3S2Br5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to two equivalent S(1), one Br(1), two equivalent Br(2), and three equivalent Br(3) atoms. In the second Nd site, Nd(2) is bonded in a 8-coordinate geometry to four equivalent S(1), two equivalent Br(1), and two equivalent Br(2) atoms. S(1) is bonded to two equivalent Nd(1) and two equivalent Nd(2) atoms to form a mixture of corner and edge-sharing SNd4 tetrahedra. There are three inequivalent Br sites. In the first Br site, Br(3) is bonded in a distorted T-shaped geometry to three equivalent Nd(1) atoms. In the second Br site, Br(1) is bonded in a 4-coordinate geometry to two equivalent Nd(1) and two equivalent Nd(2) atoms. In the third Br site, Br(2) is bonded in a 3-coordinate geometry to one Nd(2) and two equivalent Nd(1) atoms.

In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to two equivalent S(1), one Br(1), two equivalent Br(2), and three equivalent Br(3) atoms. There is one shorter (2.81 Å) and one longer (2.82 Å) Nd(1)-S(1) bond length. The Nd(1)-Br(1) bond length is 3.60 Å. There is one shorter (2.99 Å) and one longer (3.00 Å) Nd(1)-Br(2) bond length. There are a spread of Nd(1)-Br(3) bond distances ranging from 2.97-3.26 Å. In the second Nd site, Nd(2) is bonded in a 8-coordinate geometry to four equivalent S(1), two equivalent Br(1), and two equivalent Br(2) atoms. All Nd(2)-S(1) bond lengths are 2.87 Å. There is one shorter (3.04 Å) and one longer (3.05 Å) Nd(2)-Br(1) bond length. Both Nd(2)-Br(2) bond lengths are 3.33 Å.
