The structure described by Np(PS3)4 crystallizes in the tetragonal I4_1/a space group. Np(1) is bonded in a 8-coordinate geometry to four equivalent S(2) and four equivalent S(3) atoms. P(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form edge-sharing PS4 tetrahedra. There are three inequivalent S sites. In the first S site, S(3) is bonded in an L-shaped geometry to one Np(1) and one P(1) atom. In the second S site, S(1) is bonded in an L-shaped geometry to two equivalent P(1) atoms. In the third S site, S(2) is bonded in an L-shaped geometry to one Np(1) and one P(1) atom. is represented by the CIF file [CIF]
