Materials Data on Y6AgTe2 by Materials Project
Y6AgTe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are six inequivalent Y sites. In the first Y site, Y is bonded in a 3-coordinate geometry to two equivalent Ag and one Te atom. Both Y–Ag bond lengths are 3.10 Å. The Y–Te bond length is 3.29 Å. In the second Y site, Y is bonded in a 5-coordinate geometry to three equivalent Ag and two equivalent Te atoms. There are two shorter (3.10 Å) and one longer (3.24 Å) Y–Ag bond lengths. Both Y–Te bond lengths are 3.18 Å. In the third Y site, Y is bonded in a 2-coordinate geometry to one Ag and one Te atom. The Y–Ag bond length is 3.42 Å. The Y–Te bond length is 3.16 Å. In the fourth Y site, Y is bonded to two equivalent Ag and three Te atoms to form distorted edge-sharing YAg2Te3 square pyramids. Both Y–Ag bond lengths are 3.03 Å. There are one shorter (3.10 Å) and two longer (3.17 Å) Y–Te bond lengths. In the fifth Y site, Y is bonded in a 4-coordinate geometry to one Ag and four Te atoms. The Y–Ag bond length is 3.76 Å. There are a spread of Y–Te bond distances ranging from 3.10–3.38 Å. In the sixth Y site, Y is bonded in a 4-coordinate geometry to four Te atoms. All Y–Te bond lengths are 3.14 Å. Ag is bonded in a 9-coordinate geometry to nine Y atoms. There are two inequivalent Te sites. In the first Te site, Te is bonded in a 8-coordinate geometry to eight Y atoms. In the second Te site, Te is bonded to seven Y atoms to form distorted edge-sharing TeY7 pentagonal bipyramids.
