Nd4MnS7 crystallizes in the hexagonal P6_3 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 7-coordinate geometry to one S(3), three equivalent S(1), and three equivalent S(2) atoms. In the second Nd site, Nd(2) is bonded in a distorted rectangular see-saw-like geometry to one S(3) and three equivalent S(2) atoms. Mn(1) is bonded in a 3-coordinate geometry to six equivalent S(1) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent Nd(1) and two equivalent Mn(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to one Nd(2) and three equivalent Nd(1) atoms. In the third S site, S(3) is bonded in a tetrahedral geometry to one Nd(2) and three equivalent Nd(1) atoms.

In the first Nd site, Nd(1) is bonded in a 7-coordinate geometry to one S(3), three equivalent S(1), and three equivalent S(2) atoms. The Nd(1)-S(3) bond length is 2.73 Å. There are a spread of Nd(1)-S(1) bond distances ranging from 2.88-3.00 Å. There are a spread of Nd(1)-S(2) bond distances ranging from 2.86-3.30 Å. In the second Nd site, Nd(2) is bonded in a distorted rectangular see-saw-like geometry to one S(3) and three equivalent S(2) atoms. The Nd(2)-S(3) bond length is 2.67 Å. All Nd(2)-S(2) bond lengths are 2.69 Å. Mn(1) is bonded in a 3-coordinate geometry to six equivalent S(1) atoms. There are three shorter (2.40 Å) and three longer (3.12 Å) Mn(1)-S(1) bond lengths. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent Nd(1) and two equivalent Mn(1) atoms. In the second S site, S(2) is bonded in a distorted rectangular see-saw-like geometry to one Nd(2) and three equivalent Nd(1) atoms.
