Pr2PbS4 crystallizes in the tetragonal I-42d space group. Pr(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted corner, face, and edge-sharing PrS8 hexagonal bipyramids. Pb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to four equivalent Pr(1) and two equivalent Pb(1) atoms.
Pr2PbS4 crystallizes in the tetragonal I-42d space group. Pr(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted corner, face, and edge-sharing PrS8 hexagonal bipyramids. There are a spread of Pr(1)-S(1) bond distances ranging from 2.89-3.13 Å. Pb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are four shorter (2.99 Å) and four longer (3.16 Å) Pb(1)-S(1) bond lengths. S(1) is bonded in a 6-coordinate geometry to four equivalent Pr(1) and two equivalent Pb(1) atoms.
