Materials Data on Y2S2F by Materials Project
Y2S2F crystallizes in the tetragonal P4/mmm space group. The structure is one-dimensional and consists of one Y2S2F ribbon oriented in the (0, 0, 1) direction. Y is bonded in a linear geometry to one S and one F atom. The Y–S bond length is 2.44 Å. The Y–F bond length is 2.17 Å. S is bonded in a distorted linear geometry to one Y and one S atom. The S–S bond length is 1.97 Å. F is bonded in a linear geometry to two equivalent Y atoms.
