Materials Data on Eu3(SF2)2 by Materials Project
Eu3F4S2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Eu+2.67+ sites. In the first Eu+2.67+ site, Eu+2.67+ is bonded in a body-centered cubic geometry to eight equivalent F1- atoms. All Eu–F bond lengths are 2.42 Å. In the second Eu+2.67+ site, Eu+2.67+ is bonded in a 9-coordinate geometry to five equivalent S2- and four equivalent F1- atoms. There are one shorter (2.84 Å) and four longer (2.92 Å) Eu–S bond lengths. All Eu–F bond lengths are 2.62 Å. S2- is bonded in a 5-coordinate geometry to five equivalent Eu+2.67+ atoms. F1- is bonded to four Eu+2.67+ atoms to form a mixture of distorted edge and corner-sharing FEu4 tetrahedra.
