Materials Data on Sm2Se2F by Materials Project
Sm2Se2F crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Sm2Se2F cluster. Sm+2.50+ is bonded in a linear geometry to one Se2- and one F1- atom. The Sm–Se bond length is 2.83 Å. The Sm–F bond length is 2.21 Å. Se2- is bonded in a 1-coordinate geometry to one Sm+2.50+ atom. F1- is bonded in a linear geometry to two equivalent Sm+2.50+ atoms.
