Materials Data on Sm2CdSe4 by Materials Project

Sm2CdSe4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are a spread of Sm–Se bond distances ranging from 2.90–3.34 Å. Cd2+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. There are four shorter (2.82 Å) and four longer (3.38 Å) Cd–Se bond lengths. Se2- is bonded in a 6-coordinate geometry to four equivalent Sm3+ and two equivalent Cd2+ atoms.
