Materials Data on SmSF by Materials Project
SmSF is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm3+ is bonded in a 9-coordinate geometry to five equivalent S2- and four equivalent F1- atoms. All Sm–S bond lengths are 2.89 Å. All Sm–F bond lengths are 2.51 Å. S2- is bonded in a 5-coordinate geometry to five equivalent Sm3+ atoms. F1- is bonded to four equivalent Sm3+ atoms to form a mixture of distorted edge and corner-sharing FSm4 tetrahedra.
