Title: Materials Data on Er7(AgTe)2 by Materials Project

Abstract

Er7(AgTe)2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are four inequivalent Er sites. In the first Er site, Er is bonded in a 4-coordinate geometry to two equivalent Ag and two equivalent Te atoms. Both Er–Ag bond lengths are 3.01 Å. Both Er–Te bond lengths are 3.10 Å. In the second Er site, Er is bonded in a 3-coordinate geometry to three Te atoms. There are two shorter (3.24 Å) and one longer (3.28 Å) Er–Te bond lengths. In the third Er site, Er is bonded to two equivalent Ag and three Te atoms to form a mixture of distorted edge, corner, and face-sharing ErAg2Te3 trigonal bipyramids. Both Er–Ag bond lengths are 2.97 Å. There are one shorter (3.08 Å) and two longer (3.15 Å) Er–Te bond lengths. In the fourth Er site, Er is bonded in a 4-coordinate geometry to three equivalent Ag and one Te atom. There are two shorter (2.91 Å) and one longer (3.18 Å) Er–Ag bond lengths. The Er–Te bond length is 3.13 Å. Ag is bonded in a 7-coordinate geometry to seven Er atoms. There are two inequivalent Te sites. In the first Te site, Te is bonded inmore » a 8-coordinate geometry to eight Er atoms. In the second Te site, Te is bonded to seven Er atoms to form distorted edge-sharing TeEr7 pentagonal bipyramids.« less
