Materials Data on PrSF by Materials Project
PrSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr3+ is bonded in a 9-coordinate geometry to five equivalent S2- and four equivalent F1- atoms. There are one shorter (2.93 Å) and four longer (2.95 Å) Pr–S bond lengths. All Pr–F bond lengths are 2.57 Å. S2- is bonded in a 5-coordinate geometry to five equivalent Pr3+ and four equivalent F1- atoms. All S–F bond lengths are 3.18 Å. F1- is bonded to four equivalent Pr3+ and four equivalent S2- atoms to form a mixture of distorted edge and face-sharing FPr4S4 tetrahedra.
