The structure described by Nb3(BiS3)2 crystallizes in the hexagonal P-62m space group. Nb(1,2) is bonded to two equivalent S(4) and four equivalent S(1) atoms to form distorted edge-sharing NbS6 pentagonal pyramids. Bi(1) is bonded in a linear geometry to one S(1) and one S(2) atom. There are four inequivalent S sites. In the first S site, S(1) is bonded in a rectangular see-saw-like geometry to three equivalent Nb(1,2) and one Bi(1) atom. In the second S site, S(2) is bonded in a rectangular see-saw-like geometry to three equivalent Nb(1,2) and one Bi(1) atom. In the third S site, S(3) is bonded in a distorted T-shaped geometry to three equivalent Nb(1,2) atoms. In the fourth S site, S(4) is bonded in a distorted T-shaped geometry to three equivalent Nb(1,2) atoms. is represented by the CIF card [CIF]
