Materials Data on CeSF by Materials Project
CeSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce3+ is bonded in a 9-coordinate geometry to five equivalent S2- and four equivalent F1- atoms. There are one shorter (2.90 Å) and four longer (2.91 Å) Ce–S bond lengths. All Ce–F bond lengths are 2.57 Å. S2- is bonded in a 5-coordinate geometry to five equivalent Ce3+ atoms. F1- is bonded to four equivalent Ce3+ atoms to form a mixture of distorted corner and edge-sharing FCe4 tetrahedra.
