Materials Data on Y6Te2Pd by Materials Project
Y6PdTe2 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 4-coordinate geometry to four Te atoms. There are two shorter (3.11 Å) and two longer (3.13 Å) Y–Te bond lengths. In the second Y site, Y is bonded in a 3-coordinate geometry to two equivalent Pd and one Te atom. Both Y–Pd bond lengths are 3.00 Å. The Y–Te bond length is 3.31 Å. In the third Y site, Y is bonded in a 2-coordinate geometry to one Pd and one Te atom. The Y–Pd bond length is 3.35 Å. The Y–Te bond length is 3.14 Å. In the fourth Y site, Y is bonded in a 5-coordinate geometry to three equivalent Pd and two equivalent Te atoms. There are two shorter (2.98 Å) and one longer (3.25 Å) Y–Pd bond lengths. Both Y–Te bond lengths are 3.22 Å. In the fifth Y site, Y is bonded in a 4-coordinate geometry to one Pd and four Te atoms. The Y–Pd bond length is 3.74 Å. There are a spread of Y–Te bond distances ranging from 3.08–3.34 Å. In the sixth Y site, Y is bonded to two equivalent Pd and three Te atoms to form distorted edge-sharing YTe3Pd2 trigonal bipyramids. Both Y–Pd bond lengths are 2.94 Å. There are one shorter (3.09 Å) and two longer (3.21 Å) Y–Te bond lengths. Pd 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.
