Materials Data on Eu2CuTe4 by Materials Project
Eu2CuTe4 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are four shorter (3.32 Å) and four longer (3.44 Å) Eu–Te bond lengths. Cu2+ is bonded to four equivalent Te2- atoms to form corner-sharing CuTe4 tetrahedra. All Cu–Te bond lengths are 2.65 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 6-coordinate geometry to four equivalent Eu3+ and two equivalent Cu2+ atoms. In the second Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent Eu3+ and four equivalent Te2- atoms. All Te–Te bond lengths are 3.16 Å.
