Materials Data on Sm2S2F by Materials Project
Sm2S2F crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Sm2S2F cluster. Sm+2.50+ is bonded in a linear geometry to one S2- and one F1- atom. The Sm–S bond length is 2.53 Å. The Sm–F bond length is 2.23 Å. S2- is bonded in a distorted single-bond geometry to one Sm+2.50+ atom. F1- is bonded in a linear geometry to two equivalent Sm+2.50+ atoms.
