Title: Materials Data on Er2CdS4 by Materials Project

Abstract

Er2CdS4 is Spinel-like structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are ten inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to four S2- atoms to form ErS4 tetrahedra that share corners with three equivalent CdS6 octahedra and corners with nine ErS6 octahedra. The corner-sharing octahedra tilt angles range from 57–59°. There are three shorter (2.58 Å) and one longer (2.60 Å) Er–S bond lengths. In the second Er3+ site, Er3+ is bonded to four S2- atoms to form ErS4 tetrahedra that share corners with three equivalent CdS6 octahedra and corners with nine ErS6 octahedra. The corner-sharing octahedral tilt angles are 58°. There are three shorter (2.58 Å) and one longer (2.61 Å) Er–S bond lengths.
