Materials Data on TaPbS2 by Materials Project
TaPbS2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ta is bonded to six equivalent S atoms to form distorted edge-sharing TaS6 pentagonal pyramids. All Ta–S bond lengths are 2.49 Å. Pb is bonded in a distorted linear geometry to two equivalent S atoms. Both Pb–S bond lengths are 2.96 Å. S is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ta and one Pb atom.
