Materials Data on PrSO by Materials Project

PrSO is alpha Pu-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Pr4+ is bonded in a 4-coordinate geometry to two equivalent S2- and four equivalent O2- atoms. Both Pr–S bond lengths are 3.04 Å. There are a spread of Pr–O bond distances ranging from 2.34–2.45 Å. S2- is bonded in a 3-coordinate geometry to two equivalent Pr4+ and one S2- atom. The S–S bond length is 2.10 Å. O2- is bonded to four equivalent Pr4+ atoms to form a mixture of distorted edge and corner-sharing OPr4 tetrahedra.

Materials Data on PrSO by Materials Project

PrSO crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Pr4+ is bonded in a 8-coordinate geometry to four equivalent S2- and four equivalent O2- atoms. All Pr–S bond lengths are 3.15 Å. There are two shorter (2.37 Å) and two longer (2.41 Å) Pr–O bond lengths. S2- is bonded in a 5-coordinate geometry to four equivalent Pr4+ and one S2- atom. The S–S bond length is 2.11 Å. O2- is bonded to four equivalent Pr4+ atoms to form a mixture of distorted corner and edge-sharing OPr4 tetrahedra.
