资源简介：
Dy4Te7 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 9-coordinate geometry to nine Te+1.71- atoms. There are a spread of Dy–Te bond distances ranging from 3.20–3.26 Å. In the second Dy3+ site, Dy3+ is bonded to seven Te+1.71- atoms to form a mixture of distorted corner, edge, and face-sharing DyTe7 pentagonal bipyramids. There are a spread of Dy–Te bond distances ranging from 3.13–3.22 Å. There are four inequivalent Te+1.71- sites. In the first Te+1.71- site, Te+1.71- is bonded to five Dy3+ atoms to form a mixture of distorted corner and edge-sharing TeDy5 trigonal bipyramids. In the second Te+1.71- site, Te+1.71- is bonded to five Dy3+ atoms to form a mixture of distorted corner and edge-sharing TeDy5 trigonal bipyramids. In the third Te+1.71- site, Te+1.71- is bonded in a 8-coordinate geometry to four equivalent Dy3+ and four equivalent Te+1.71- atoms. All Te–Te bond lengths are 3.09 Å. In the fourth Te+1.71- site, Te+1.71- is bonded in a 4-coordinate geometry to four equivalent Dy3+ atoms.
