PrS2 crystallizes in the monoclinic P2_1/c space group. Pr(1) is bonded in a 9-coordinate geometry to four equivalent S(2) and five equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to five equivalent Pr(1) atoms to form a mixture of distorted corner and edge-sharing SPr5 trigonal bipyramids. In the second S site, S(2) is bonded in a distorted pentagonal planar geometry to four equivalent Pr(1) and one S(2) atom.
PrS2 crystallizes in the monoclinic P2_1/c space group. Pr(1) is bonded in a 9-coordinate geometry to four equivalent S(2) and five equivalent S(1) atoms. There are a spread of Pr(1)-S(2) bond distances ranging from 2.88-3.20 Å. There are a spread of Pr(1)-S(1) bond distances ranging from 2.87-3.15 Å. There are two inequivalent S sites.
