Materials Data on Er2CdSe4 by Materials Project

Kristin Persson
Er2CdSe4 is Spinel-like structured and crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are eleven inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to four Se2- atoms to form ErSe4 tetrahedra that share corners with three equivalent CdSe6 octahedra and corners with nine ErSe6 octahedra. The corner-sharing octahedra tilt angles range from 58–59°. There are three shorter (2.70 Å) and one longer (2.72 Å) Er–Se bond lengths. In...
