Materials Data on Eu(YS2)2 by Materials Project
Eu(YS2)2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Eu2+ is bonded to eight equivalent S2- atoms to form distorted edge-sharing EuS8 hexagonal bipyramids. There are four shorter (2.87 Å) and four longer (3.07 Å) Eu–S bond lengths. Y3+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are a spread of Y–S bond distances ranging from 2.75–3.07 Å. S2- is bonded in a 6-coordinate geometry to two equivalent Eu2+ and four equivalent Y3+ atoms.
