The structure described by P2NbS8 crystallizes in the tetragonal P-4n2 space group. Nb(1) is bonded in a 8-coordinate geometry to two equivalent S(2), two equivalent S(4), and four equivalent S(1) atoms. P(1) is bonded to one S(2), one S(4), and two equivalent S(3) atoms to form corner-sharing PS4 tetrahedra. There are four inequivalent S sites. In the first S site, S(4) is bonded in an L-shaped geometry to one Nb(1) and one P(1) atom. In the second S site, S(1) is bonded in a 3-coordinate geometry to two equivalent Nb(1) and one S(1) atom. In the third S site, S(2) is bonded in an L-shaped geometry to one Nb(1) and one P(1) atom. In the fourth S site, S(3) is bonded in a water-like geometry to two equivalent P(1) atoms. is represented by the CIF card [CIF]
