The Materials Project

MgEr2Se4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Mg2+ is bonded in a 4-coordinate geometry to eight equivalent Se2- atoms. There are four shorter (2.73 Å) and four longer (3.29 Å) Mg–Se bond lengths. Er3+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are a spread of Er–Se bond distances ranging from 2.80–3.26 Å. Se2- is bonded in a 6-coordinate geometry to two equivalent Mg2+ and four equivalent Er3+ atoms.
